| Description: | 1. High heat resistance 3000 ¡æ sublimation, its strength at room temperature 1800 ¡æ two times, 1500 ¡æ dozens of air-cooled to room temperature does not break down, in an inert gas in 2800 ¡æ do not soften. 2. high thermal conductivity and hot products for the 33W/MK iron, as in more than 530 ¡æ thermal conductivity of ceramic materials is the largest materials. 3. low thermal expansion coefficient of expansion coefficient of 2 × 10-6 second only to quartz glass, is the smallest ceramic, with its high thermal conductivity, thermal shock resistance so good. 4. excellent electrical properties, good heat insulation, 25 ¡æ for the 1014Ω-CM, 2000 ¡æ can be achieved 103Ω-CM, is the best high-temperature ceramic insulation materials, breakdown voltage 3KV/MM, low-k power loss 108HZ when 2.5×10-4, a dielectric constant of 4, through the microwave and infrared. 5. good corrosion resistance and general metal (iron, copper, aluminum, lead), rare earth metals, precious mostly, semiconductor materials (germanium, silicon, GaAs), glass, molten salt (crystals, fluoride , slag), inorganic acids, alkalis do not respond. 6. low friction coefficient u of 0.16, high temperature is not increased, compared with molybdenum disulfide, graphite, high temperature, oxidizing atmosphere can be used to 900 ¡æ, can be used under vacuum to 2000 ¡æ. 7. B of high purity with a high impurity content of less than 10PPM, and with B is greater than 43.6%. 8. to machining of the Mohs hardness 2, so the method can be processed into general machining high precision parts and components products. The use of hexagonal boron nitride can be used to make TiB2/BN hexagonal boron nitride composite ceramics can also be used for advanced refractory and superhard materials, level with the separation of ring rolling, high-temperature coatings for high temperature lubricant and is also synthesis of Cubic boron Nitride materials. | |
