Application field

    1 Coatings, plastics, rubber and other fillers: High-purity magnesium oxide can be used as a filler for paints, papers and cosmetics, as fillers and reinforcing agents for plastics and rubber, and as auxiliary materials for various electronic materials due to its high dispersibility.

    2 High performance ceramics: High purity 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: Due to their high activity and high dispersibility, high-purity magnesium oxide is easily compounded with high polymers or other materials. 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: High-purity 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 materials: High-purity magnesium oxide has good flame retardant effect. It can be used together with wood chips and shavings to produce refractory materials such as light weight, sound insulation, heat insulation and refractory fiberboard, as well as cermets.

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.
