Quartz crystals are formed through hydrothermal synthesis in pressure vessels with thermal jackets and heating coils. The process involves crushed feeding quartz and NaOH solution heated to over 300°C under pressure exceeding 1000 bars, producing crystals weighing up to several kilograms.
We are piezo wafer specialists with 30 years of experience in Single Crystal Quartz manufacturing. We export millions of quartz blanks annually and master AT, SC, and IT cuts with superior angle precision. Our expertise extends to LiNbO3, LiTaO3, Quartz glass, LGS, and CTGS materials.
