quartz glass crucible

we can supply cylinder quartz crucible, square quartz crucible, music crucible and etc

Crucible: According to factory standards require that for every 100 cubic centimeters of the surface of the crucible coating not less than 1.44g, may also be required several times with the coating method, coating weight of double or more Quartz products: including quartz boats and diffusion tubes, etc., the inner surface of the coating weight of> 1g/100c Other coatings and purification of products: o purification of products: semiconductor devices in order to avoid closed-tube diffusion process and manufacture of gallium arsenide single crystals, etc. inside the vessel due to quartz impurity ion diffusion caused by the contamination, the company has established with HCl gas at a high temperature purification of quartz containers Technology o The purification of the product, heavy metal impurities less than the original product multiplied o such products are used in silicon, when the proliferation of closed-tube, test results show that the silicon wafer minority carrier lifetime can increase to more than double Al2O3 and SiC coating products: o In order to improve the use of diffusion tube deformation softening temperature of the outer surface of the tube coated with a layer of high-purity Al2O3 and their sintering o This coating products in the 1300 ° C under the deformation rate lower than 60% of uncoated products o the use of a SiC coating, it could be 1300 under the deformation rate of 80% reduction in test o In addition to the outer surface of the coating can improve the use of quartz tube temperature, the impurity ions can block the outside world to the quartz tube wall penetration, thus ensuring the quality of silicon circuits semiconductor industry with high-purity quartz crucible arc method arc method using a semiconductor is drawn semi-transparent quartz crucible large-diameter silicon, an essential foundation for the development of large scale integrated circuit materials high purity, strong heat resistance, size large, high precision, good insulation, energy conservation, the advantages of stable quality
