Most quartz acclimated in chip is produced synthetically. Large, absolute and untwinned crystals are produced in an alter via the hydrothermal process. The action involves alleviative ashamed accustomed quartz with hot aqueous band-aid of a abject such as sodium hydroxide. The hydroxide serves as a "mineralizer", i.e. it helps deliquesce the "nutrient" quartz. High temperatures are required, generally about 675 °C. The attenuated quartz again recrystallizes at a berry clear at hardly lower temperatures. Approximately 200 bags of quartz were produced in the US in 2005; ample amalgam accessories abide throughout the world. Synthetic quartz is generally evaluated on the base of its Q factor, a admeasurement of its piezoelectric acknowledgment and an indicator of the abstention of the crystal.9
High-temperature bottle composed of silicon dioxide with no (or alone baby amounts of) added apparatus is referred to as "quartz glass" or alloyed quartz, although it is baggy in structure, rather than crystalline
