Product Details
Quartz Materials Hydrothermal Growth of Quartz: 1. The autoclave is filled to some predetermined factor with water plus mineralizer (NaOH or Na2CO3). 2. The baffle localizes the temperature gradient so that each zone is nearly isothermal. 3. The seeds are thin slices of (usually) Z-cut single crystals. 4. The nutrient consists of small (~2½ to 4 cm) pieces of single-crystal quartz (“lascas”). 5. The temperatures and pressures are typically about 3500C and 800 to 2,000 atmospheres; T2 - T1 is typically 40C to 100C.? ? 6.The nutrient dissolves slowly (30 to 260 days per run), diffuses to the growth zone, and deposits onto the seeds. CQT supply piezo single crystal blanks, which include quartz materials and quartz blanks. We has been servicing for microelectronic manufacturers, defense related contractors, National laboratories, universities and scientists around the world since 1990 Product Parameters 1.Physical properties of synthetic crystal quartz Density, g/cm3 2.65 Melting point, °C 1467 Thermal conductivity, W/(m? x?
