5-500mm high boron nitride ceramic cylinder

The 5-500mm high boron nitride ceramic cylinder is a high-performance special ceramic material, which is made of high-purity boron nitride (BN) powder through high-temperature hot pressing sintering or cold isostatic pressing molding process. This product has excellent high temperature resistance, insulation, thermal conductivity and chemical stability, and is suitable for industrial applications in extreme environments.
Product characteristics
-High temperature resistance: it can work stably in the high temperature environment above 1000 ° C, and can withstand the high temperature of 1800 ° C in the short term.
-High thermal conductivity: high thermal conductivity (about 30-60 W/m · K) and anisotropy, suitable for scenarios with high heat dissipation requirements.
-Electrical insulation: high resistivity (>10 ^ 14 Ω· cm), suitable for high-voltage and high-frequency electronic equipment.
-Low friction coefficient: excellent self-lubricating performance, reducing mechanical wear.
-Chemical inertia: resistant to acid and alkali corrosion, not reacting with most molten metals, suitable for metallurgical industry.
-Strong machinability: it can be precisely machined into different sizes and shapes to meet the customized requirements.

Product advantages and problem solving
(1) Solve the problem of material failure under high temperature environment
Traditional metals or ordinary ceramics are easy to be oxidized and deformed at high temperatures, while boron nitride ceramic cylinders remain stable above 1000 ° C, extending equipment life.
(2) Improve the heat dissipation efficiency of electronic equipment
High thermal conductivity can effectively reduce the operating temperature of electronic components to avoid overheating damage.
(3) Reduce mechanical wear and maintenance costs
Self lubrication features reduce friction loss, suitable for high wear environment, and reduce downtime for maintenance.
(4) Adapt to harsh chemical environment
Corrosion resistance makes it suitable for acid, alkali and molten metal environment to avoid material degradation.
