[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Preferred embodiments of the present invention will be described in detail below. According to the present invention, a burial product is obtained by forming a tourma statue or the like from a single piece of tourmaline or quartz powder having excellent heat resistance and firing it. The burial items are mainly composed of tourmaline, a natural mineral, and mixed with quartz, a natural mineral, as needed. Tourmaline and quartz are used as building materials and materials for fine arts and ceramics.They have the desired heat resistance and can be molded into beautiful and sophisticated forms. It is. The cremation cremation is molded into a desired shape, pre-fired at a temperature of 1000 ° C. or less, subjected to desired cutting and finishing, and then fully fired at a high temperature of about 1200 ° C. to obtain a product. Cremation burials, when cremated with their bodies, are covered with a cloth-like protective material made of ceramics to prevent rapid heating and quenching to prevent damage and cracks, and contamination with gases and combustion residues generated during cremation. At the same time, the funeral items are prevented from being heated to a temperature higher than the firing temperature at the time of manufacture.
[0010]
Tourmaline is a natural mineral also called tourmaline, and 11 types are currently confirmed. Tourmaline is a gaseous mineral represented by the chemical composition of XY ₃ AL ₆ (BO ₃ ) ₃ (Si ₆ O ₁₈ ) (OH) _{4 and made} of a gas containing boron, and belongs to a hexagonal system. It is a fine columnar, needle-like or columnar crystal. Hardness is 7 to 7.5, specific gravity is 3.0 to 3.25, glassy and has resin gloss, and various colors such as black, black brown, blue black, blue, green, red, brown, white, and colorless Present. Depending on the components, iron tourmaline, magnesite tourmaline, lithiae tourmaline, acroite tourmaline, lime-mica tourmaline, red tourmaline, chrome dryite tourmaline, indigo tourmaline, redi coat tourmaline, green and yellow tourmaline etc. Are classified into 11 types of tourmaline. When tourmaline reaches 1230 ° C., the original effect of tourmaline is lost, so firing at 1200 ° C. or lower is required. It is known that tourmaline is charged with heat or friction and emits far-infrared rays to generate negative ions.
[0011]
Quartz has excellent resistance to thermal shock due to its excellent high-temperature electrical resistance and low coefficient of thermal expansion, and has strong spalling resistance to thermal shock against sudden temperature rise during cremation and rapid cooling after cremation. Because it is mixed with tourmaline, it is suitable for improving the resistance of burial articles to rapid heat and rapid cooling. Although the melting point of quartz is 1710 ° C., but the upper limit for continuous use is 1200 ° C., it can be fired at a firing temperature of 1200 ° C. or less, which is the same as for tourmaline.
[0012]
The burial article of the present invention, which is composed of tourmaline alone or a mixture with quartz, is fired at a firing temperature of 1200 ° C. Since the firing temperature of 1200 ° C. matches the maximum temperature during cremation, it is expected that the temperature will be 1200 ° C. or higher when the burial product is placed near the incineration burner. Therefore, the burial product of the present invention is covered with a ceramics-made cloth-like protective material and insulated to prevent overheating at 1200 ° C. or more, and to prevent breakage and cracks due to rapid cooling and rapid heating. The cloth-like protective material is made of ceramic wool, fiber, felt, paper, or the like. The ceramic wool or fiber is made of a material mainly composed of alumina or silica. Quartz fiber, which is a ceramic fiber, is completely fused silica as a product, has a high melting point and excellent weather resistance and chemical resistance compared to glass fiber, but when used continuously at 1000 ° C or more for a long time. It has the disadvantage that mullite and cristobalite precipitate and the fibers are hard and brittle. Therefore, alumina and a silicate substance such as kaolin, bauxite, kyanite, and refractory clay are mixed. A fiber having a fused silica and alumina ratio of about 50 to 50 is a fiber that can withstand a use temperature of 1260 to 1300 ° C, and a fused silica 40 and alumina 60 can be a fiber that can withstand a use temperature of 1600 ° C. Alternatively, titanium oxide, borate glass, zirconia, or the like may be added in a small amount and melted at a high temperature of 2000 ° C. or more to obtain a fiber, which may be formed into a woven cloth, a compressed felt, or a paper. Further, by wrapping the burial goods with ceramic wool and wrapping the exterior with ceramic cloth, the heat insulation effect can be further enhanced.
[0013]
The Buddha statue as a burial product may be formed by any of molding methods such as cast molding, dry pressure molding, semi-dry pressure molding, and plastic molding, but the mud-recommended casting method is the simplest. Other methods require large machines and expensive dies and are costly. Mud casting is performed by casting a chiller consisting of a suspension or colloidal solution of tourmaline or quartz powder into a two- or three-piece mold that is molded from plaster with gypsum to form a Buddha statue and dry it. Thereafter, it is calcined at 1000 ° C. or less. Since the temporarily baked Buddha statue is soft, it is subjected to processing such as removing the burrs and necessary cavities for storing the ashes, and a plane portion for attaching a plaque, and then sintering at 1200 ° C.

【Example】
Preferred embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a Buddha image (1) which is a burial item according to the present invention. The type and form of the Buddha statue vary depending on the sect and use, and are appropriately selected. The Buddha statue in FIG. 1 is made of tourmaline and is cast into a mold after mixing with mud. Water and a dispersing agent are added to the tourmaline powder as a raw material and stirred well. The dispersant is added to reduce the water content as much as possible, and the amount of the dispersant is adjusted to around 1500 cps at which the viscosity becomes minimum. The tourmaline was selected from white lime-magnesite tourmaline, having a particle size of 32.5 mesh and a purity of 99%. As the dispersant, Alon A-6114 manufactured by Toagosei Co., Ltd. was used. The cast gypsum mold, which is a cast mold, is obtained by applying a mold release agent to a wood carved Buddha statue, which is a prototype, by mixing gypsum in which water is mixed with gypsum plaster powder, and curing the mixture. Since the shape is complicated, the gypsum mold was divided into three. The mud of the tourmaline is poured into a cast gypsum mold, and the mud is cast. After casting, the compact shrinks and tends to separate from the mold. Since the Buddha statue taken out of the mold is still wet, heat is applied to sufficiently evaporate the water and drying is performed.
[0015]
After drying, the calcination starts. The calcination is performed by increasing the temperature of the dried Buddha statue by 100 ° C. per hour until the temperature reaches 800 ° C. to 900 ° C., and then keeping the temperature for 1 hour. After calcination, it is still soft, so burrs and small parts are removed when the mold is removed, and a space (2) for accommodating ashes is recessed as shown in Figs. Then, as shown in FIGS. 6 and 7, the flat portion (3) for attaching the tablet is cut. By adopting the pre-firing step, it is possible to easily remove burrs, perform correction processing or other processing, and to minimize shrinkage during the main firing. The main firing is performed in an electric furnace at a rate of 100 ° C. per hour, and at a temperature of 1200 ° C., the temperature is maintained for 1 hour, and is performed for 13 hours. The space (2) formed on the back of the Buddha statue in FIGS. 2 and 3 is filled with the same material as the Buddha statue or a kaname plate after the ashes are stored. The space (2) formed below the Buddha image in FIGS. 4 and 5 is closed with a cap (4). Even in the case of molding with a material in which quartz is mixed with tourmaline, casting is performed in the same manner as in the case where the tourmaline alone is used as a raw material, and after preliminary firing, main firing is performed. Quartz powder having a particle size of 32.5 mesh and a purity of 98 to 99% was used. Tourmaline and quartz were mixed at a ratio of 50:50, a dispersant was added, and the mixture was stirred well to obtain a mud.
[0016]
When cremating with the body, wrap the Buddha statue (1) with ceramic wool (5) as shown in FIG. 8, then wrap the outer surface with a cloth-like protective material covered with ceramic cloth (6) and put it in a coffin. . By coating with the ceramic wool (5) and the ceramic cloth (6), it was confirmed that the temperature of the Buddha image main body was kept at 1000 ° C. or less. That is, the Buddha statue was covered with ceramic wool (5) and ceramic cloth (6), the temperature was rapidly raised to 1200 ° C. and held for one hour, and the temperature of the Buddha statue in the cloth-like protective material was measured with a thermocouple. It did not rise above 1000 ° C. Thereafter, the mixture was rapidly cooled to room temperature, but no trouble occurred.
