Abstract
High-purity and good sinterable mullite powder (3Al₂O₃･2SiO₂) was synthesized by a sol-gel process to prepare a high-purity mullite crucible. The densified mullite crucible was fabricated by slip casting with the powder followed by sintering at 1600 ℃. Solar salt was put into the mullite crucible and then fired at the..... More

Abstract
Cordierite was synthesized using multi-component materials based on a talc-alumina-clay system. The cordierite sintered at 1360 °C showed a high relative density of 98.8% and a low thermal expansion coefficient of 1.59×10^-6/°C. To study the effect of adding alkaline-earth minerals on the cordierite properties, petalite, potash-feldspar, and dicalcium phosphate were..... More
