Boron nitride ceramic products

Product Advantages:

Boron nitride ceramic parts have good heat resistance, thermal stability, thermal conductivity and high-temperature dielectric strength, making them ideal applications for heat dissipation and high-temperature insulation environments.

Boron nitride ceramics have good chemical stability, can resist the erosion of most molten metals, and have excellent self-lubricating properties.

Applications:

Hexagonal boron nitride ceramics can withstand high temperatures in high vacuum environments and have excellent corrosion resistance and corrosion resistance. Therefore, BN ceramic products are ideal for many industries such as:

• Crucibles used for melting semiconductors;
• High temperature vessels for metallurgy;
• Semiconductor heat dissipation and insulation parts;
• High temperature bearings;
• Thermowell;
• Glass forming mold.

Product Performance:

• High heat resistance: sublimates at 3000°C; at 1800°C, its strength is twice that of room temperature. It will not break when cooled from 1500℃ to room temperature dozens of times; it will not become soft in an inert gas at 2800℃.
• High conductivity: hot pressed products are 33W/M·K, which is the same as pure iron. It has maximum thermal conductivity above 530℃.
• Low thermal expansion coefficient: Its thermal expansion coefficient is 2×10^-6, second only to quartz glass and the lowest among ceramics. High thermal shock resistance due to high thermal conductivity.
• Excellent electrical properties: Excellent high temperature insulation; up to 10¹⁴Ω·cm at 25℃ and 10³Ω·cm at 2000℃. So it is the best insulating material among high temperature ceramics. When the breakdown voltage is 3KV/MM, the low dielectric loss is 10⁸HZ, it can reach 2.5×10^-4, the dielectric constant is 4, and it can penetrate microwave and infrared rays.
• Extremely strong corrosion resistance: It will not react with ordinary metals (iron, copper, aluminum, lead, etc.), rare earth metals, precious metals, semiconductor materials (germanium, silicon, potassium arsenide), glass, molten salt (crystal) , fluoride and slag), inorganic acids and bases.
• Low friction coefficient: u is 0.16 and will not increase at high temperatures. It has higher high temperature resistance than molybdenum disulfide and graphite. The oxidizing atmosphere is 900°C; it can be used at 2000°C under vacuum.
• High purity and high boron content: the impurity content is less than 10PPM and the boron content exceeds 43.6%.
• Machinability: Its hardness is Mohs 2, so it can be processed into high-precision parts and components through conventional machining.
