Hebei Messi Biology Co., Ltd. stated that high specific surface area magnesium oxide is an important raw material for the preparation of high-performance precision inorganic materials, electronic components, inks, and harmful gas adsorbents. This type of magnesium oxide has extremely high chemical activity and physical adsorption capacity due to its fine particles and a large ratio of surface atoms to bulk atoms. Due to its excellent sintering performance, it can be made into highly dense fine-grained ceramics or multifunctional magnesium oxide films, and at the same time has high activity and high dispersibility, and is easy to be compounded with polymers or other materials.
As an accelerator and activator for butyl rubber, chloroprene rubber, styrene-butadiene rubber and fluororubber; the activity of magnesium oxide can increase the cross-linking density of butyl rubber, thereby improving the physical properties of rubber bottle stoppers; used as fillers for adhesives, plastics, paints and paper. In medicine, it is used as an antacid and laxative for gastric acid hyperacidity and duodenal ulcers; it has excellent alkali resistance and electrical insulation at high temperatures, high thermal expansion coefficient and thermal conductivity, and excellent light projection.
Due to its fine particles, the ratio of surface atoms to bulk atoms is large, which makes it extremely chemically active and physically adsorbable. Due to the presence of a large number of surface atoms and surface defects, the diffusion rate of surface atoms is very high, so it has good sintering performance. Using high-activity nano-scale powdered magnesium oxide, low-temperature sintering can be achieved without the use of sintering aids, and high-density fine-grained ceramics or multifunctional magnesium oxide films can be made, which are expected to be developed into cutting-edge materials under harsh conditions such as high temperature and high corrosion.
Due to its high activity and high dispersibility, it can even be made into fibrous magnesium oxide, which is easy to be compounded with polymers or other materials. This composite material has good microwave absorption performance, and at the same time does not reduce the strength, toughness and other indicators of the raw materials, and the addition of fibrous magnesium oxide also has a reinforcing effect. Magnesium oxide can also be used as a sintering aid and stabilizer for other nanoparticles such as zirconium oxide, aluminum oxide, and iron oxide to obtain high-quality nanophase ceramics. In addition, due to its high dispersibility, this magnesium oxide can also be used as a filler for paints, paper and cosmetics, a filler and reinforcing agent for plastics and rubber, and an auxiliary material for various electronic materials.
