Purification

Bay Composites offers a unique high-temperature purification process that removes metals and gases left behind in the graphite manufacturing process. Removing residual traces of these impurities will make your graphite parts last longer, and perform more consistently. 

We have three levels of purification to suit all industrial and semiconductor needs. 

  • High purity - 20 ppm or less 

  • CVP purity - 5 ppm or less 

  • Semiconductor purity - 0.05 ppm or less.
