Hebei Messi Biology Co., Ltd. stated that electronic components generally use oxide ceramics, and magnesium oxide has greater surface activity and high-temperature characteristics, so it is the main raw material in oxide ceramics. In the research and development of high-purity and high-density electronic component materials, high-purity magnesium oxide uses its own characteristics and uses magnesium oxide with a purity of more than 99.5% as a raw material to ensure the purity of electronic components.
The high-purity nano magnesium oxide independently developed and produced by Hebei Messi Biology Co., Ltd. is widely used in high-temperature heat-resistant materials, ceramic materials, electronic substrates and other materials. High-purity nano magnesium oxide is produced using advanced technology, with a purity of more than 99.95% and an average particle size of 10nm. Compared with traditional processes, it has the advantages of high product purity, fine particle size, large specific surface area, and good dispersion. It has excellent alkali resistance and electrical insulation at high temperatures, high thermal expansion coefficient and thermal conductivity, and good light transmittance. It also has good sintering performance. Low-temperature sintering can be achieved without the use of sintering aids to produce high-density fine-grained ceramics or multifunctional magnesium oxide films, which are expected to be developed into electronic component materials under harsh conditions such as high temperature and high corrosion.
The demand for magnesium oxide for electronic ceramics is mainly concentrated on piezoelectric ceramics. The purity of magnesium oxide is required to be above 99.5%. The dielectric loss of ceramic capacitors is small and the material uniformity is good. It is suitable for the production of multilayer ceramic capacitors with large capacity, high insulation resistivity and ultra-thin dielectric layer (dielectric layer thickness is less than 10μm). The addition amount is 0.5-5%. Magnesium oxide for electronic ceramics has special requirements, such as particle size distribution, crystal structure, fineness, activity, heavy metals, whiteness, iron, wear resistance, high temperature resistance, etc. These can be customized according to specific special requirements.
