Boron Nitride Rod

TPBN is a high-purity boron nitride material. It is commonly used in applications where exceptional purity and chemical stability are required, such as in the production of crucibles for handling high-purity materials.
What sets TPBN apart from other boron nitride materials is its superior purity. Boron nitride is typically synthesized through chemical vapor deposition or hot pressing, which can result in impurities and defects in the final product. However, TPBN is produced using a specialized thermal purification process that removes impurities and ensures a high level of consistency and uniformity throughout the material.
The thermal purification process involves heating the raw boron nitride material to temperatures above 2,000 degrees Celsius in an inert atmosphere. This causes any impurities and contaminants to volatilize and separate from the purified boron nitride. The resulting TPBN material has a low concentration of impurities,especially calcium, making it ideal for use in the production of crucibles for high-purity materials.
In addition to its exceptional purity, TPBN also exhibits excellent chemical stability and resistance to thermal shock.
Overall, TPBN is a specialized boron nitride material that offers exceptional purity and chemical stability, making it an ideal choice for the production of crucibles for high-purity materials. Its unique thermal purification process ensures a high degree of consistency and uniformity, providing engineers and designers with a reliable and high-quality material for their most demanding projects.
