Advantages Of Hexagonal Boron Nitride Ring

Boron nitride ceramic ring has good heat resistance, thermal stability, thermal conductivity and high temperature dielectric strength, which is an ideal application in heat dissipation and high temperature insulation environment.

The boron nitride ceramic ring has good chemical stability, can resist the erosion of most molten metals, and it has excellent self-lubricating properties.

Boron Nitride Ring Applications

The hexagonal boron nitride ceramics made by Great Ceramic can withstand high temperature in high vacuum environment, and have excellent corrosion resistance and resistance. Therefore, BN ceramic products are the ideal choice for many industries, such as:

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

Boron Nitride (HBN) Basic Information

• High heat resistance: sublimation at 3000°C; at 1800°C, its strength is twice that at room temperature. It will not break when cooled from 1500°C to room temperature dozens of times; it will not become soft in an inert gas at 2800°C.

• High conductivity: The hot-pressed product is 33W/MK, the same as pure iron. When it is higher than 530℃, it has the 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. Due to its high thermal conductivity, it has high thermal shock resistance.

• Excellent electrical properties: excellent high-temperature insulation; up to 10¹⁴Ω-cm at 25°C and 10³Ω-cm at 2000°C. So it is the best high temperature. Insulating material in ceramics. When the breakdown voltage is 3KV/MV, 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: Will not react with common 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 alkalis.

• Low friction coefficient: U is 0.16, which will not increase at high temperature. It has higher 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 by conventional machining.
