Process for producing high purity fused quartz powder

摘要

High purity fused silica particles are made by heating relatively low density silica flour in a high temperature flame. The silica flour feed rate, flame temperature, and collection zone temperature are adjusted to produce an aggregate of surface-bonded fused silica parti­cles. The aggregate is shaped like a honeycomb and can be ground autogenously without introducing impurities into the final product.
