Silicon oxide ceramic slurry containing mullite whisker precursor as well as preparation method and application of silicon oxide ceramic slurry
The invention provides silicon oxide ceramic slurry containing a mullite whisker precursor and a preparation method and application of the silicon oxide ceramic slurry, the silicon oxide ceramic slurry comprises ceramic powder and photosensitive resin premixed liquid, and the addition amount of the ceramic powder is 40-65% of the total volume of the slurry; the ceramic powder comprises the following raw materials in percentage by weight: 80-90wt% of quartz glass powder; 5-15 wt% of a mineralizing agent; 3 to 12 wt% of aluminum fluoride; 1-3 wt% of a catalyst; the photosensitive resin premixed liquid comprises the following raw materials by weight: 30-60 wt% of a resin oligomer; 30 to 60 wt% of a resin monomer; 2 to 4 wt% of a photoinitiator; and 5-10 wt% of a dispersant. The introduction of the mullite whiskers can improve the interlayer strength and shrinkage rate of the ceramic core.
本发明提供了一种含有莫来石晶须前驱体的氧化硅陶瓷浆料及其制备方法和应用，氧化硅陶瓷浆料包括陶瓷粉体与光敏树脂预混液，所述陶瓷粉体的添加量为浆料总体积的40‑65％；所述陶瓷粉体包括如下重量百分比的原料：石英玻璃粉：80‑90wt％；矿化剂：5‑15wt％；氟化铝：3‑12wt％；催化剂：1‑3wt％；所述光敏树脂预混液包括如下重量百分比的原料：树脂低聚物：30‑60wt％；树脂单体：30‑60wt％；光引发剂：2‑4wt％；分散剂：5‑10wt％。本发明中莫来石晶须的引入能够改善陶瓷型芯的层间强度及收缩率。
