China Boron Nitride Hbn Special Ceramics

Product Introduction
___________________________________________________________Hexagonal boron nitride is a good conductor of heat, an electrical insulator, and has the lubricating properties of a wolf. Therefore, hexagonal boron nitride is widely used in ceramic manufacturing, such as crucibles, evaporation boats for aluminum plating, circuit board substrates and high-temperature lubricants industries, and is used in the preparation of hexagonal boron nitride and can also be used as an atomic reactor. Structural materials and rocket engine blocks.H-BN-C (3-5μm): Small particle size, high crystallinity, suitable for applications with small particle size requirements, such as thermal tape and thermal film additive; thermal fiber product additives; demoulding Used as a preparation for cubic boron nitride; special ceramic raw materials.
Product Parameters
____________________________________________________________Application
____________________________________________________________1. High heat resistance: oxidation starts at 900 °C in an oxidizing atmosphere, safely can be used up to 2000 °C under vacuum, anManipulator d does not soften at 2800 °C in an inert gas; its strength is 1800 °C twice as much as room temperature.2. High thermal conductivity: the hot-pressed product is 33W/m·k, which is the same as pure iron. Above 530°C, it is the most thermally conductive material in ceramic materials;3. Low thermal expansion coefficient: The expansion coefficient of 2x10-6 is second only to quartz glass, which is the smallest among ceramics.4. Excellent electrical properties: good high temperature insulation, 1014 Ω-cm at 25 °C, 103 Ω-cm at 2000 °C, the best high temperature insulation material in ceramics, breakdown voltage is 3KV/mm. Low dielectric loss, 2~5x10-4 at 108HManufacturing Equipment for Electrical & ElAlarm & Security Systems ectroni z, dielectric constant of 4, transparent microwave and infrared;5. Good corrosion resistance: with general metals (iron, copper, aluminum, lead, etc.), rare earth metals, precious metals, semiconductor materials (silicon, silicon, potassium arsenide,), glass, molten salt (crystal, fluorine) Compound, slag), inorganic acid, alkali do not react;6. Low friction coefficient: μ is 0.16, and does not increase at high temperature;
