Preparation method of fused quartz ceramic
The invention relates to the field of fused quartz ceramics, and discloses a fused quartz ceramic preparation method, which comprises: 1, preparing materials, fused quartz sand and water; 2, matching and grinding quartz sand and water into fine slurry according to a proportion, and putting the fine slurry into a stirring tank for aging for later use; 3, mixing and stirring the quartz sand with different granularities and the fine slurry according to a ratio, putting the mixture into a pressure tank, and vacuumizing by stirring; fourthly, conducting heating forming through a grouting plaster mold and a gel injection water bath, and conducting natural airing for 2-3 days; 5, water is dried in a drying furnace, and firing is conducted in a shuttle kiln, according to the preparation method of the fused quartz ceramic, microwave-vacuum combined roasting is adopted, gas-liquid inclusion in quartz bursts and escapes through the characteristic of selective microwave heating, under the vacuum condition, B, P and other elements are volatilized, and hydroxyl in quartz sand is effectively removed.
本发明涉及熔融石英陶瓷领域，且公开了一种熔融石英陶瓷制备方法，包括以下步骤：第一步：准备好材料，熔融石英砂、水；第二步：石英砂和水按比例配磨成细浆，放到搅拌罐陈腐备用；第三步：不同粒度的石英砂和细浆按比例混合搅拌，放入压力罐抽搅拌真空；第四步：注浆石膏模具和注凝水浴加热成型，自然晾干2‑3天；第五步：先在烘干炉中烘干水分，梭式窑烧制，该熔融石英陶瓷制备方法，采用微波‑真空联合焙烧，通过微波选择性加热的特点使石英中的气液包裹体爆裂并逸出，在真空的条件下，使B、P等元素挥发，并且将石英砂中的羟基得到有效的去除。
