We have excellent technology development capabilities, the high purity fused quartz crucibles for the solar grade mono-crystalline silicon application. At present we have eight product lines of Quartz Crucible. Our quartz crucibles are available in a range of standard sizes from 12 to 28 inches in diameter, and in custom-made drawing. In addition to the available compositions, we will prepare to work on your specific crucible designs. We can also produce special types according to client's technical[...]

Cutting fluids are often used in silicon processing to achieve favorable results. Water is a cooling agent for high speed, high temperature grinding operations. Cutting fluids that promote ductile, also negatively impact the machining process by increasing tool wear, which have no smell and are also of no harm to a human body.[...]
