| Name︰ | High purity synthetic quartz coating transparent quartz glass crucible |
| Country of Origin︰ | China |

| Specifications︰ | Now there are 2 sorts quartz glass products for semiconductors in China according to purity:molten from nature crystal,impurity contents(Al、e、Ca、Mg、Ti、Ni、Cu、Co、Mn、B、K、Na、Liect)<50ppm,and molten through high temperature hydrolysis from high pure tetrachlosilane,impurity of these metals<2ppm,but this product is very enpensive,besides soft point is 80’c lower than that of quartz glass made from rock crystal, and the rucible,diffusion tube made from it becom deformed in use. Our company using low cost, high soft point of quartz products and high purity of synthetic quartz ,has produced the high purity synthetic quartz coating quartz glass products,the technology is putting a layer of high pure synthetic quartz glass into the internal wall of crystal quartz glass through hight temperature spray coating. Thus we have the advantages of both quartz glass products. |
