The lace is kneaded by hand, then dried, molded and hardened into a desired shape, and then fired, or the above ceramic raw material is made into a slurry, the lace is immersed in this slurry-like ceramic M1 raw material, and the lace is pulled out to form the slurry. The lace is impregnated with the lace, and then the lace is dried to form and harden into a desired shape, and then fired to form an imitation lace.

ないといった不満がある。``Problems to be Solved by the Invention'' However, in the above manufacturing method, since ceramic raw materials mixed with plastic clay are used, the strength of the unfired molded body in the molded and hardened state is insufficient, making it difficult to manufacture. This unfired molded body is often broken inside, etc., resulting in a disadvantage that the yield is poor. In addition, since the strength of the unfired molded body is insufficient, it is necessary to apply a large amount of ceramic raw material to the lace in advance to prevent the molded body from collapsing when the lace is burned out during firing. However, as a result, the resulting ceramic imitation lace is thick, and there are complaints that the delicate patterns of the lace cannot be sufficiently reproduced.

It is preferable to obtain a mixture of α-type tricalcium phosphate and tetracalcium phosphate by a thermal decomposition method obtained by dehydrogenation at a high temperature of 00° C. or higher. That is, in this way α
When a mixture of type tricalcium phosphate and tetracalcium phosphate IN is obtained, the resulting mixture can be, for example, a mixture obtained by treating dibasic calcium phosphate and calcium carbonate at a high temperature of 1200°C or higher, or α-type phosphorus. This is because it has a more homogeneous chemical composition than a mixture obtained by separately synthesizing tricalcium acid and tetracalcium phosphate and dry mixing them, and the hydrated hardened product obtained from this has higher strength. .

Here, the acid is preferably phosphoric acid, and the salt is preferably a phosphate. This is because phosphoric acid or a phosphate salt accelerates curing, and the phosphate ions in the phosphoric acid or phosphate aqueous solution are incorporated into the structure of the hydrated product, so it does not reduce heat resistance. It is.

程度にまで含浸量を調整するのが望ましい。A method of impregnating the lace with a slurry-like mixture obtained by adding a kneading liquid to the ceramic raw material powder is a method of kneading the slurry into the lace by hand once or twice, or a method of soaking the lace in the slurry. Methods such as spraying slurry onto the lace, etc. are applied. After impregnating the lace with the slurry using these methods, it is desirable to squeeze out excess slurry and adjust the amount of impregnation to such an extent that the lace pattern is clearly visible.

。"Function" According to the method for manufacturing imitation ceramic lace of the present invention, the binder is a water-curing material that hardens by reacting with water, and the obtained eternally hardened material has excellent heat resistance. By using a binder, the lace impregnated with ceramic raw materials has sufficiently high strength in the unfired shape that is molded and hardened, and even after the lace disappears during ceramic firing, the lace remains strong in the ceramic. The shape of the green compact is maintained until the sintering temperature is reached.

パタイトを生成させる方法を採用した。First, a mixture of α-type tricalcium phosphate and tetracalcium phosphate with a molar ratio of calcium to phosphorus of 1.65 was obtained by a thermal decomposition method obtained by dehydrogenating hydroxyapatite at a high temperature of 1200°C or higher. . In this case, the method for obtaining hydroxyapatite is to synthesize α-type tricalcium phosphate and tetracalcium phosphate by treating dibasic calcium phosphate and calcium carbonate at a high temperature of 1200°C or higher, since the synthesis is simple. , then this α
A method was adopted in which water was added to a mixture of tricalcium phosphate and tetracalcium phosphate, and hydroxyapatite was produced through the Eiwa reaction.

。"Effects of the Invention" As explained above, the method for manufacturing imitation ceramic lace of the present invention uses a binder which is a water-curable material and which makes the obtained permanent hardened material excellent in heat resistance. As a result, the lace impregnated with ceramic raw materials has sufficiently high strength in the unfired molded state that has been molded and hardened, thereby preventing breakage during manufacturing, thereby achieving a high yield. become something that can be done. Furthermore, since the cured product of the binder has excellent heat resistance, it maintains sufficient strength up to the firing temperature of ceramics, and therefore, it is prevented from breaking during firing, further increasing the yield. In addition, even after the lace disappears during ceramic firing, the shape of the unfired compact is maintained until the sintering temperature of the ceramic is reached, so the amount of ceramic raw material impregnated into the lace can be reduced. The imitation lace obtained by this method exhibits the same delicate lace pattern as the original lace.
