China Boron Nitride Hbn Special Ceramics

Product Introduction
___________________________________________________________
HBN-A: Medium crystallization, excellent high temperature and oxidation resistance, small original particle size and large agglomerate size. Because the particles are spherical, they are especially suitable as fillers, casting and injection molding release agents and composite ceramics, and are also easy to hot press.To reach or close to the advanced level of similar foreign products, it can replace imports. Main raw materials for preparing special composite ceramics, such as evaporation boat for aluminum plating; raw materials for hot-pressed boron nitride products; lubricating coating additives; metal surface trResistor & Potentiometer eatment addition; used for preparing cubic boron nitride; demoulding in casting molding and injection molding agents, etc.Product Parameters
____________________________________________________________Application
______________________________________________Security & Protection ______________1. High heat resistance: oxidation starts at 900 °C in an oxidizing atmosphere, safely can be used up to 2000 °C under vacMould uum, and 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 108Hz, 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;
