Product Description

Product Description

Boron nitride tube also known as white graphite, has a structure similar to that of graphite. It has good electrical insulation,thermal conductivity, excellent thermal shock resistance, and Chemical stability. Boron nitride ceramics are processed by hot-pressing and sintering boron nitride powder into product blocks according to the customer's required size specifications.

The design of high-temperature furnaces operating at temperatures significantly higher than 1500°C incorporates heating elements manufactured from carbon, tungsten. As a rule, these elements are electrically insulated from the furnace sides using high-temperature oxide ceramics.
 

In this field, we can offer precision machined components such as tubes, washers, sleeves, insulators, insulating plates, spools, flanges, and other parts subjected to high thermal stresses.
