Tungsten Crucible Cover

Tungsten crucible is made of tungsten crucible cover, tungsten crucible body and tungsten crucible base part (also known as tray). Because tungsten crucible has characteristic of high temperature resistance, low coefficient of expansion, etc., so it can be used as a main carrier in sapphire single crystal growth furnace. Tungsten crucible cover’s density is about 18.3 g / cm³, and its purity can reach 99.95% above. In sapphire growth furnace, tungsten crucible cover, as an insulator assembly, whose most important role is: cut off and reflect furnace heat. Tungsten crucible cover is closely combined with tungsten crucible body, which constitutes a confined space; you need control the confined space properly in order to produce high quality sapphire crystal. In addition, the tungsten crucible cover require higher purity, accuracy size also required and the surface should be smooth, these benefits can improve the quality of pulling sapphire crystal.
