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.
