Once fired and sintered, it can only be machined using diamond-grinding methods. It features high hardness and wear resistance, low erosion levels, high temperature resistance, corrosion resistance, and bioinertness. Additionally, it can be highly polished making it useful for precision sealing applications like pumps and pistons.Alumina is an excellent high temperature ceramic material due to its high temperature stability. It is the most commonly used type of advanced ceramic and VHANDY's alumina ceramics is available in purities ranging from 95 – 99.9%. Precision Ceramics has access to many different types of Alumina including: injection molded, dry pressed, isosostatically pressed, slip cast, and extruded.SpecificationPerformance projectUnitValuePerformance projectUnitValueAlumina contentwt /%≥96Volume resistivityΩ.cm 20℃10 12 Bulk densityg/cm3≥3.7Breakdown strengthKV / mm≥15Hardness (HRA)HRA≥ 82Acid resistancemg / m2≤7Flexural strengthMPa≥ 320Alkali resistancemg / m2≤0.2Safety temperature℃-55~1480Wear resistanceg / m2≤0.2Water absorption%<0.01Compressive strengthMPa≥ 2400Coefficient of linear expansionx10-6 / ℃7.5 ~ 8.5Bending strengthMPa≥200Dielectric constantξ, 20 ° C, -1 MHz9Modulus of elasticityGPa300Dielectric losstanδx10-4, 1MHz3Thermal conductivityW / m.k (20 ℃)24 ~ 25Advantages:? The thermal expansion coefficient of the ceramic substrate is close to that of the silicon wafer, which can save the transition layer Mo film, save labor, materials, and reduce costs;? Reduce the solder layer, reduce thermal resistance, reduce gaps, and improve the yield rate;? Under the same current carrying capacity, the 0.3 mm thick copper foil is only 10% of the ordinary printed circuit board;? Excellent thermal conductivity, the chip package is very compact, which greatly improves the power density and improves the reliability of the system and devices;? Ultra-thin (0.25 mm) ceramic substrate can replace BeO, without environmental toxicity issues;? Current carrying capacity, 100A continuous current passes through 1 mm wide and 0.3 mm thick copper body, the temperature rise is about 17 ℃; 100A current passes through a continuous 2 mm wide and 0.3 mm thick copper body, the temperature rise is only about 5 ℃;? Low thermal resistance, the thermal resistance of 10 × 10 mm ceramic substrate is 0.63 mm thick and the thermal resistance of 0.31 mm thick ceramic substrate K/W, 0.38mm thickness of ceramic substrate thermal resistanceThermal resistance is 0.19k/W, 0.25mm thickness of ceramic substrate thermal resistance is 0.14k/W.High dielectric strength, personal safety and equipment protection.? Allows new packaging and assembly methods, making products highly integrated and compact.Application?
