Basic Information
Custom Rare Metal specializes in producing high purity Tellurium Bars at the range of 99.99% to 99.99999%. Besides tellurium bars, tellurium shot, tellurium powder, tellurium cube and tellurium powder are available by request. The lowest possible bar unit price to tellurium metal melt value ratio is maintained through advanced smelter and mould systems refined and pressed to exacting purity and weight.
Available Forms of Tellurium Metal
- Tellurium Bar
- Tellurium Copper
- Tellurium Granule
- Tellurium Dioxide
- Tellurium Compound
Also, we produce Tellurium as rod, pellets, block, pieces, ingot, and alloys, as tiny cubes and in compound forms, such as bismuth telluride. Tellurium metals may be purchased in bulk or small quantity.
