Product Description Insulating Beryllium oxide ceramics substrate plate sheet BeO Beryllia ceramics for electronicProduct DescriptionBeryllia ceramics/Beryllium oxide ceramicsBeryllium oxide ceramics are ceramics with beryllium oxide as the main component. Mainly used as a substrate for large-scale integrated circuits, high-power gas laser tubes, heat sink shells for transistors, microwave output windows and neutron moderators.Characteristics of beryllium oxide ceramicsPure beryllium oxide (BeO) belongs to the cubic crystal system, and its density is 3.03g/cm3. The melting point is 2570oC, it has high thermal conductivity, the thermal conductivity λ is 200-250W/(m.K), and it has good thermal shock resistance. Beryllium oxide ceramics are made of beryllium oxide powder as raw material, alumina and other ingredients are added and sintered at high temperature.The melting temperature range of beryllium oxide is 2530oC~2570oC, and its theoretical density is 3.02g/cm3. It can be used for a long time at 1800oC in vacuum, 2000oC in inert gas, and 1800oC in oxidizing atmosphere. oC to volatilize. The most outstanding performance of beryllium oxide ceramics is its large thermal conductivity, which is similar to that of metal aluminum and 6 to 10 times that of aluminum oxide. It is a dielectric material with unique electrical, thermal and mechanical properties.Application of beryllium oxide ceramicsBeryllium oxide ceramics are widely used in microwave technology, electric vacuum technology, nuclear technology, microelectronics because of its high thermal conductivity, high melting point, strength, high insulation, low dielectric constant, low dielectric loss and good packaging process adaptability. It has been valued and applied in the field of optoelectronic technology, especially in high-power semiconductor devices, high-power integrated circuits, high-power microwave vacuum devices and nuclear reactors. It has always been the mainstream ceramic material for preparing high thermal conductivity components.Technique Data of Beryllium Oxide Ceramic ItemTest ConditionsSpecificationUnitB-97B-99Dielectric Constant1MHz6.90.46.90.4 (100.5)GHz Dielectric Loss Tangent1MHz≤4X 10-4≤4X 10-4 (100.5)GHz≤8X 10-4≤8X 10-4Volume Resistivity25oC≥1014≥1014Ω.cm300oC≥10"≥10"Breakdown StrengthD C≥15≥20kV/mmCMOR-≥170≥190MPaAverage Linear Expansion Coefficient25oC~500oC(7.0~8.5)*10-4(7.0~8.5)*10-4I/KThermal Conductivity25oC≥200≥240W/m.K 100oC≥160≥190Thermal Shock Resistance0oC-800oCThere should be no cracks Bulk Density ≥2.85≥2.85g/ cm3Chemical Stability1:9HCL≤0.3≤0.3Mg/cm2 10% NaOH≤0.2≤0.2 Air Tightness-≤10*10-11≤10*10-11Pa. m3/sAverage Grain Size-12~3012~30μmPackaging & ShippingCompany ProfileRongsheng Refractory is located in Xinmi city, "the Capital of Refractory" in China.
