Specifications of China High Thermal Conductivity Boron Nitride Ceramic Parts

China’s high thermal conductivity boron nitride ceramic parts deliver exceptional performance for demanding thermal management. You’ll find thermal conductivity values typically ranging from 50 W/mK to 80 W/mK in the plane of hot pressing. This high heat transfer capability is crucial. It efficiently pulls heat away from critical components.

Electrical insulation is another major benefit. These parts act as excellent electrical insulators. This property is vital. It allows safe operation in high-voltage environments. Heat moves fast, electricity does not pass through.

Temperature resistance is impressive. These ceramics withstand continuous use up to 900°C in air. Performance remains stable even higher in inert atmospheres or vacuum. This makes them suitable for extreme conditions.

Chemical inertness is a key feature. Boron nitride shows strong resistance to most molten metals. It also resists many corrosive salts and glasses. This chemical stability ensures long service life in harsh processes. Parts won’t degrade quickly.

Mechanical properties are solid. You get good strength and hardness. Density is low, usually between 1.9 g/cm³ and 2.1 g/cm³. This lightweight nature helps in overall system design. Machinability is good too. Manufacturers can machine these ceramics to precise shapes and tight tolerances before final sintering. This ensures complex geometries are possible.

Surface finish quality is consistently high. Parts exhibit low porosity. This enhances their performance and reliability. Strict quality control is maintained throughout manufacturing in China. Consistency batch-to-batch is a priority. Engineers rely on these specs for predictable results in electronics sintering, semiconductor processing, aerospace components, and metallurgy.
