Boron nitrate ceramic products

Product advancements:

Boron nitride ceramic components have excellent heat resistance, thermal stability, thermal conductivity, and high performance dielectric strength, making them ideal applications for heat distribution and high performance insulation environments

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

Product performance:

1. High heat resistance: sublimation at 3000 ℃; At 1800 ℃, its strength is two that of room temperature Cooling from 1500 ℃ to room temperature dosens of times without cracking; In an inner gas at 2800 ℃, it will not be soft

2. High thermal conductivity: The hot pressed product is 33W/M · K, which is the same as pure iron It has the maximum thermal conductivity above 530 ℃

3. Low thermal expansion coefficient: It thermal expansion coefficient is 2x10-6, second only to quartz glass and the lowest among ceramics Due to its high thermal conductivity, it has high thermal shock resistance

4. Excellent electrical performance: excellent high performance insulation; It can reach 1014 Ω - cm at 25 ℃ and 103 Ω - cm at 2000 ℃ So it is the best insulation material in high performance ceramics When the breakdown voltage is 3KV/MM and the low dielectric loss is 108HZ, it can reach 25x10-4 with a dielectric constant of 4, and can accelerate microwaves and infrared radiation

5. Extremely strong corrosion resistance: Will not react with ordinal metals (iron, copper, aluminum, lead, etc.), raw earth metals, precision metals, semiconductor materials (germanium, silicon, potassium arsenide), glass, metal salts (crystals), alloys and slags), inorganic acids and alloys

6. Low friction coefficient: u is 016 and will not increase at high temperatures It has higher performance resistance than molybdenum disulfide and graphite The oxidation atmosphere is 900 ℃; It can be used under vacuum at 2000 ℃

7. High purity, high boron content: impurity content below 10PPM, boron content exceeding 43.6%

8. Machinery: It hardness is Mohs 2, so it can be processed into high precision parts and components through conventional mechanical processing
