Production method of high-strength and high-compactness fused quartz
The invention discloses a production method of high-strength and high-compactness fused quartz. The production method comprises the following steps: (1) producing a fused quartz raw material; (2) preparing slurry, namely performing ball milling on the fused quartz raw material and cordierite by adopting a ball mill at the rotating speed of 250-300r/min in a forward and reverse ball milling mannerfor 6-10h, sieving the powder by using a 500-mesh sieve, adding the powder subjected to ball milling into a precursor solution, adding a dispersing agent, adjusting the pH value to 3-4 through lacticacid and ammonia water, and preparing slurry with the solid phase content of 60-65% through mechanical stirring; (3) conducting gel curing; (4) conducting drying; and (5) conducting microwave sintering. According to the production method of the high-strength and high-compactness fused quartz, the production method is simple and efficient, the influence of impurity elements on the chemical stability, strength and compactness of the high-strength and high-compactness fused quartz is avoided, and the prepared fused quartz has good breaking strength, high compactness, good chemical stability and wide application prospects.
