Boron Nitride Ring

Boron nitride rings are high-performance ceramic components made of boron nitride material. They have excellent thermal and chemical stability, high electrical insulation properties, and low thermal expansion coefficients. They are commonly used in high-temperature and high-vacuum applications where traditional materials like metals and plastics cannot perform.

Boron nitride rings are widely used in the semiconductor industry as insulators, spacers, and chamber components due to their excellent dielectric strength, low dielectric constant, and low loss tangent. They are also used in high-temperature furnaces, vacuum furnaces, and heat treatment applications.
