The properties and applications of ultrafine magnesium oxide

Ultrafine magnesium oxide is a new type of particulate material.It has a white powder appearance,high purity,large specific surface area,and is composed of extremely fine grains.It is non-toxic,odorless,and has good dispersibility,with a relative density of about 3.58(25℃).Melting point 2852℃,boiling point 3600℃.It is insoluble in water,insoluble in alcohol,and soluble in acid or ammonium salt sol

            Ultrafine rubber stopper is a new type of particulate material.It has a white powder appearance,high purity,large specific surface area,and is composed of extremely fine grains.It is non-toxic,odorless,and has good dispersibility,with a relative density of about 3.58(25℃).Melting point 2852℃,boiling point 3600℃.It is insoluble in water,insoluble in alcohol,and soluble in acid or ammonium salt solutions.After being burned at high temperatures above 1000℃,it can be transformed into crystals.After modification treatment,there is no agglomeration phenomenon,and it has many special functions and important application values in optics,catalysis,magnetism,mechanics,chemical engineering,etc.It has a very broad prospect and is an important new material in the 21st century.

            High purity fused magnesium oxide has excellent alkali resistance and electrical insulation at high temperatures.High thermal expansion coefficient and thermal conductivity have good light transmittance.Widely used as high-temperature and heat-resistant materials,it is used as a raw material for transparent ceramic crucibles,substrates,etc.in the field of ceramics.In electrical materials,it is used as a filler for magnetic devices,insulation materials,and various carriers.When used as a ceramic substrate,its thermal conductivity is more than twice that of alumina,and the electrolyte loss is only 1/10 of alumina.

            Ultrafine powder magnesium oxide can also be used as a sintering aid and stabilizer for other nanoparticles such as zirconia,alumina,and iron oxide to obtain high-quality nano phase ceramics.In addition,due to its high dispersibility,this ultrafine magnesium oxide can also be used as a filler for paints,paper,and cosmetics,as well as a filler and reinforcing agent for plastic box rubber,and as an auxiliary material for various electronic materials.
