Ultrafine magnesium oxide is a new type of particulate material with white powder. It has high purity and large specific surface area. It is composed of extremely fine crystal grains. It is non-toxic, odorless and has good dispersibility. The relative density is about 3.58 (25 ° C). The temperature of 2852 ° C, the boiling point of 3600 ° C. Hardly soluble in water, insoluble in alcohol, soluble in acid or ammonium salt solution. It can be converted into crystals by burning at a temperature above 1000 °C. After modification, there is no agglomeration phenomenon, and it has many special functions and important application values in optics, catalysis, magnetism, mechanics and chemical industry. The prospect is very broad and it is an important new material in the 21st century.
Ultrafine magnesium oxide application:
(1) Coatings, plastics, rubber and other fillers: Ultra-fine magnesium oxide can be used as filler for paints, papers and cosmetics, fillers and reinforcing agents for plastics and rubber, and auxiliary materials for various electronic materials due to its high dispersibility. .
(2) High performance ceramics: Ultrafine magnesium oxide has good sintering properties. 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 produced, and it is expected to be developed as a cutting-edge material under severe conditions such as high temperature and high corrosion.
(3) Absorbing materials: Ultrafine magnesium oxide is easily compounded with high polymers or other materials due to its high activity and high dispersibility. The composite material has good microwave absorption performance, and does not reduce the strength and toughness of the raw material, and the addition of fibrous magnesium oxide has a reinforcing effect.
(4) Adsorbents and catalysts: Ultrafine magnesium oxide has a large specific surface area and is an important raw material for preparing high-performance fine inorganic materials, electronic components, inks, and harmful gas adsorbents.
(5) Flame-retardant material: Ultra-fine magnesium oxide has good flame retardant effect, and can be used together with wood chips and shavings to produce refractory materials such as light weight, sound insulation, heat insulation and refractory fiberboard, and cermet.
(6) Others: fuel additives, detergents, antistatic agents and anti-corrosion agents, electrical insulator materials, manufacturing crucibles, furnaces, insulated conduits (tubular components), electrode rods, electrode sheets, etc.
(7) Using cotton anti-static finishing agent formulated with MgO to perform functional finishing on cotton fabric and polyester fabric, the antistatic performance test results show that the finished fabric has better antistatic effect.
Magnesium oxide is an excellent filler and reinforcing agent for rubber products. It can improve the quality and strength of rubber products. It can also be used in the manufacture of high-grade glass products, adhesives, paints and household chemicals. Ultra-fine magnesium oxide is light in weight. Good activity characteristics, can be used for paper fillers, accelerators and activators of chlorine rubber and fluororubber, and have important value in the plastics industry.
