Product Description

alpha Al2O3 nanoparticles powder for ceramic

Alpha-alumina has been widely used in the production of various new ceramic materials due to its high strength, high hardness, high temperature resistance, wear resistance and a series of excellent properties. It is not only used as a powder raw material for advanced alumina ceramics such as integrated circuit substrates, artificial gems, cutting tools, artificial bones, etc., but also used as phosphor carriers, advanced refractory materials, special abrasive materials, etc. With the development of modern science and technology, the application fields of α-alumina are rapidly expanding, and the market demand is also increasing, and its prospects are very broad.

1. Spark plug insulating ceramicSpark plug insulating ceramics is currently the single largest application of ceramics in engines. Because alumina has excellent electrical insulation, high mechanical strength, high pressure resistance and thermal shock resistance, alumina insulated spark plugs are widely used in the world. The requirement of alpha-alumina for spark plugs is ordinary low-sodium alpha aluminum monoxide micropowder, in which the sodium oxide content is ≤0.05%, and the average particle size is 325 mesh.

2. Integrated circuit substrate and packaging materialsCeramics used as substrate materials and packaging materials are superior to plastics in the following aspects: high insulation resistance, high chemical resistance, high sealing, can prevent moisture from passing through, non-reactive, and will not pollute ultra-pure semiconductor silicon.

3. High pressure sodium luminous tube

Fine ceramics made of high-purity ultra-fine alumina as raw materials have the characteristics of high temperature resistance, corrosion resistance, good insulation, and high strength. It is an excellent optical ceramic material. A transparent polycrystal made of high-purity alumina with a small amount of magnesium oxide, lanthanum oxide or iridium oxide and other additives, using atmosphere sintering and hot pressing sintering methods, can withstand the corrosion of high-temperature sodium vapor, and can be used as a high-pressure sodium light-emitting tube , Its lighting efficiency is high.

Application of α-alumina in bioceramicsAs inorganic biomedical materials, bioceramic materials have no toxic or side effects compared with metal materials and polymer materials, and have good biocompatibility and corrosion resistance with biological tissues. People have paid more and more attention to them. The research and clinical application of ceramic materials have developed from short-term replacement and filling to permanent and firm planting, from biologically inert materials to biologically active materials and multiphase composite materials.
