HEAT-RESISTANT CLAY RAW MATERIAL AND HEAT-RESISTANT PORCELAIN
To provide a heat-resistant clay raw material, which is a raw material for heat-resistant porcelain having sufficient durability for practical use, and a heat-resistant porcelain obtained as a fired product of the heat-resistant clay raw material.SOLUTION: A heat-resistant clay raw material includes clay, a fused quartz, and a strength-enhancing material. The strength-enhancing material is at least one of an iron-source material and a magnesium-source material, the bending strength of a fired product formed with the heat-resistant clay raw material is 10% or greater than the bending strength of a fired product formed with a heat-resistant clay raw material having the same composition except not including the strength-enhancing material, the heat-resistant clay raw material contains 0.1 to 80 mass% of strength-improving material relative to the whole of the heat-resistant clay raw material and the linear expansion coefficient of the fired product of the heat-resistant clay raw material is 0.1 to 5.0×10-6/K from room temperature to 700°C.SELECTED DRAWING: None
【課題】実用上十分な耐久性を備える耐熱陶磁器の原料となる耐熱粘土原料、および、この耐熱粘土原料の焼成体として得られる耐熱陶磁器を提供する。【解決手段】耐熱粘土原料は、粘土、溶融石英、および強度向上材を含み、強度向上材は、鉄供給源となる物質およびマグネシウム供給源となる物質の少なくともいずれかであり、耐熱粘土原料の焼成体の曲げ強度が、強度向上材を含まないこと以外は同じ構成の耐熱粘土原料の焼成体の曲げ強度よりも１０％以上大きく、耐熱粘土原料は、強度向上材を耐熱粘土原料全体に対して０．１～８０質量％含み、耐熱粘土原料の焼成体は、室温から７００℃における線膨張係数が０．１～５．０×１０-6／Ｋである。【選択図】なし
