(Prior Art) Recently, ceramic products are desired to have high mechanical strength, that is, bending strength, and especially in the field of tableware, there is a demand for improved strength in order to eliminate "splashing" caused by machine washing.

った。For this reason, approximately 3 Q wt. Research has been conducted on alumina-reinforced porcelain to which % of alumina is added, and some with bending strength of approximately 200 MPa are commercially available. The components of typical conventional alumina-reinforced porcelain are 30 wt% alumina, 30 wt% feldspar (Ohira feldspar), and 30 wt% 221 Zealand Kaolin.
, 10 wt% of frog's eye clay. However, this strong porcelain has lost the elegant translucency of feldspathic monosilica-kaolinite porcelain and lacks aesthetic value as tableware. The reason for this is that alpha crystals of alumina are formed in the porcelain, and the reflectance of this material is different from the reflectance of the matrix portion. (Purpose) The present invention provides reinforced porcelain with translucent properties. (Structure) The present invention removes the alumina component in porcelain by 20wt% or less, preferably completely, and removes aluminum phosphate by 10wt% or less.
This relates to a feldspar-silica-kaolinite-based translucent reinforced porcelain containing 50 wt% of wt%, and its composition is based on the following experimental results. That is, the porcelain raw material having the composition shown in Table 1 was prepared to a thickness of 2 m using a conventional method.
The flexural strength and translucency of each sheet were measured by molding it into a plate-like body of 500 m and firing it at 1,200°C to 1,350°C and setting the water absorption rate to 0%. Table 1 Translucency (brightness) was measured using Spectrophotom.
eter (manufactured by Murakami Color Research Institute) CMS-500 was used. From these results, it is preferable that alumina be 20 wt% or less or 0, and AIP○4 be 10 wt% to 50 wt%. Note that if the clay content is less than 20 wt%, the molding ability will decrease, so it is necessary to keep it at least 20 wt%. Furthermore, the raw material composition of the present invention has little deformation during firing. (Example) Molded products made of raw materials having the composition shown in Table 3 were fired at the temperatures shown in the table. Table 3 The bending strength and translucency of each of the above-mentioned Example products were as shown in Table 4.

適なものでる。Table 4 (Effects) As is clear from the values in Tables 2 and 4, the product of the present invention has strength comparable to conventional alumina-reinforced porcelain, and has a brightness equivalent to bone porcelain. Furthermore, it has excellent moldability, making it suitable for use as tableware or ceramics for ornaments.
