We have excellent technology development capabilities, our  high purity fused quartz crucibles are used in the solar grade mono-crystalline silicon and the manufacture of poly-crystalline silicon solar cells.
Our quartz crucibles are available in a range of standard sizes from *0 to *2 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 data and drawing.
