Process of making high quality single quartz crystal using silica glass nutrient
摘要
Ultra high pure quartz is grown by a one step in-situ growth process where the nutrient is high purity silica. A negative temperature gradient is maintained between the nutrient zone and the seed zone until about the start of crystal growth. A sealable container made of silver contains the nutrient and the seed within the autoclave chamber.
