Nano-magnesium oxide is a new type of highly functional fine inorganic material, the main types of which are nano-powder, nano-film, nano-filament and nano-solid. Due to the specificity of its structure, it is determined to have different electrical, magnetic, thermal and optical properties from the body, thus opening up a series of new application areas. High purity nano magnesium oxide appearance white powder, high purity, large specific surface area, composed of very fine grains, odorless, good dispersion.
First, nano magnesium oxide (VK-Mg30) in the application of nanophase ceramics Nano magnesium oxide in ceramics can be used as a sintering additive, nano-ceramics from unagglomerated nano-powder titanium oxide, alumina, etc. by static sintering or stress-assisted sintering. However, due to the high surface energy of nanopowders, surface activity, higher grain boundaries can provide a higher driving force for the growth of crystals at the same time also triggered a decrease in the adhesive strength of the grain boundaries, nano-magnesium oxide as a sintering additive in nanophase ceramics, can effectively solve this problem. In the nano-zirconia powder doped with 5% of nano-magnesium oxide, through the stress-free sintering successfully made a high-density ceramics.
Second, nano-magnesium oxide (VK-Mg30) in the application of catalyst Nano-magnesium oxide crystals as a catalyst for alkyl chlorination, can adsorb a large number of chlorine formed Cl2 – magnesium oxide adducts in magnesium oxide nanocrystals due to the chlorine atoms and the surface of the O2 – anion share the density of electron cloud, when chlorine dissociation chemisorption occurs, the chlorine-like ions are encapsulated, and therefore the Cl2 – magnesium oxide adducts chemical reactivity is closer to the chloride ion than that of chlorine gas, and the selectivity of Cl2-MgO adducts is higher than that of chlorine atoms. The use of nanomagnesium oxide with certain pretreatment as catalyst can increase the yield of the product of the process of ethyl phthalide acetone by catalytic synthesis from 80% to 95%. Nano magnesium oxide also has high catalytic activity for the polymerization of bismalein phthalimide (BMI).
Third, high purity nano-magnesium oxide (VK-Mg20) in the field of electronic applications: electronic components are generally selected oxide ceramics, due to magnesium oxide has a large surface activity and high temperature characteristics, so it is the main raw material in the oxide ceramics. In the research and development of high purity, high density electronic components materials, magnesium oxide with its own characteristics, using the purity of 99.95% or more magnesium oxide as raw materials, to ensure the purity of electronic components. High purity nano-magnesium oxide is produced by advanced process, the purity is above 99.95 %, the average particle size is 10nm, which has the advantages of high purity, fine particle size, large specific surface area, good dispersion and so on compared with the traditional process. It has excellent alkali resistance and electrical insulation at high temperature, high coefficient of thermal expansion and thermal conductivity, and good light transmittance. It also has good sintering performance. Do not need to use sintering additives can be realized at low temperature sintering, made of high density fine crystal ceramics or multifunctional magnesium oxide film, can be expected to be developed for high temperature, high corrosion and other harsh conditions of the electronic components materials.
Fourth, nano-magnesium oxide in the cable rubber field: nano-magnesium oxide (VK-Mg30) for rubber cables, mining cables, marine cables and other industries, can make the cable to improve corrosion, acid resistance, high temperature resistance and other properties, to improve the stability of the work of the harsh conditions.
Fifth, nano magnesium oxide (VK-Mg30) in the textile field, with the increasing demand for high-performance flame retardant fibers, the synthesis of new high-performance flame retardant high purity magnesium oxide (VK-Mg30) for the development of functional fabrics provide ideal materials. In addition, nano-magnesium oxide (VK-Mg30) for fuel has a strong clean, inhibit corrosion ability, there are good prospects for application in paint.
Six, nano-magnesium oxide (VK-Mg30) used in different products play different roles, in the chemical fiber, plastics industry for flame retardant; silicon steel sheet production of high-temperature annealing agent, high-grade ceramic materials, electronic industrial materials, chemical raw materials in the binder and additives; radio industry, high-frequency rod antennae, magnetic device filler, insulating materials filler and a variety of carriers; refractory fibers and refractories, magnesium-chromium bricks, heat-resistant coatings filler, and the use of the material.
