XTL Sintyron 99.7% hexagonal boron nitride pbn bushing ceramic ring

Boron nitride ceramic rings are a type of ceramic component made from boron nitride material. Boron nitride is a high-performance ceramic with excellent thermal conductivity, high temperature resistance, and chemical inertness. These ceramic rings are commonly used in high-temperature and high-vacuum environments where traditional metal or plastic components may not be suitable. Boron nitride ceramic rings are often used as seals, bearings, insulators, or protective coatings in various industrial applications such as semiconductor manufacturing, aerospace, and automotive industries. Due to their exceptional properties, boron nitride ceramic rings are highly valued for their durability, reliability, and performance in extreme conditions.
