What is Quartz Quartz Crystal SiO2 Electronics Notes

The process for manufacturing synthetic quartz entails dissolving raw silicon diode, SiO 2 in an alkali water solution at around 400C and under high pressure. The crystals can then be grown. This is a very slow process and often growth rates are as little as 1mm per day.
