The nano magnesium oxide powder is prepared by aerosol ablation method and has the advantages of high purity, small particle size, uniform distribution, large specific surface area, clean surface, no residual impurities, low bulk density, and easy dispersion.
There are obvious small size effect, surface effect, quantum size effect and macroscopic tunnel effect. After surface modification, there is no hard agglomeration phenomenon. In the system, there is better dispersion, higher nano activity, so as to maximize the use of nanometer The special properties of magnesium oxide particles, such as light, electricity, magnetic field, heat, and quantum effect, greatly increase the performance of traditional products, lead to a qualitative leap, and give the product new properties.
1. Nano-magnesia is used in high-performance ceramics: nano-magnesia has good sintering performance, can be sintered at low temperature without using sintering aids, and can be made into high-density fine-grained ceramics or multi-functional magnesium oxide films. Expect to develop cutting-edge materials under severe conditions such as high temperature and high corrosion;
2. Nano-magnesium oxide is used as a wave-absorbing material: Due to its high activity and high dispersibility, nano-magnesium oxide is easily compounded with high polymers or other materials. This kind of composite material has good microwave absorption performance, and at the same time it will not reduce the indexes of strength, toughness, etc. of the raw material, but also add fibrous magnesium oxide to reinforce the effect;
3, nano-magnesia powder used as paint, plastic, rubber and other fillers: nano-magnesia due to a high degree of dispersion, can be used as paint, paper and cosmetics fillers, plastic and rubber fillers and reinforcing agents and various Auxiliary materials for electronic materials;
4, nano-magnesia used for adsorbents and catalysts: nano-magnesia has a large specific surface area, is an important raw material for the preparation of high-functional fine inorganic materials, electronic components, inks, harmful gas adsorbents;
5. Nano-magnesium oxide is used as a functional flame-retardant material: Nano-magnesium oxide has a good flame-retardant effect, and it can be used together with wood chips and shavings to manufacture refractories and metal ceramics such as light weight, sound insulation, thermal insulation, and fire-resisting fiberboard. For fire-retardant coatings, the additive amount of 1%-5% would achieve the best effect.
6. Others: fuel additives, cleaning agents, antistatic agents and corrosion inhibitors, electrical insulator materials, manufacturing crucibles, furnaces, insulated conduits (tubular elements), electrode rods, electrode sheets, etc.;
7. Nano-magnesia preparation foam ceramic filter is a filter used for the purification of alloy liquid, which solves the technical problem that prior art filters do not pass through magnesium alloys and high-temperature alloys containing active elements;
8, nano-magnesia and rare earth oxide as a sintering aid, preparation of silicon nitride ceramics, can efficiently and economically produce a variety of complex shapes of products, such as cutting tools, seal rings, bearings, nozzles and a variety of high temperature, Wear-resistant, corrosion-resistant products, etc.
9. Nano-magnesium oxide is used to prepare high-toughness ceramic materials. High-purity small-grained nano-magnesia and lanthanum oxide or rare earth metal oxides are used as composite stabilizers. Zirconium ceramics. The ceramic material can be widely used as a high temperature engineering component and a high-grade refractory material.
