1. Spherical magnesium oxide
Hebei Messi Biology Co., Ltd. stated that because spherical powder is easy to achieve close packing, it has strong pressure resistance, and due to its isotropy, its properties are stable. Currently, there are two main methods to prepare spherical magnesium oxide: magnesium salt First, a precursor for preparing spherical magnesium oxide is obtained as a raw material, and the precursor is heat-treated to obtain spherical magnesium oxide; after mixing the magnesium oxide powder with a solvent and a binder, the spherical magnesium oxide is obtained through mechanical molding, and the spherical magnesium oxide product is obtained through heat treatment.
2. Flake magnesium oxide
Hebei Messi Biology Co., Ltd. stated that flaky magnesium oxide has a two-dimensional structure and is relatively easy to achieve during the preparation process. The application of flake magnesium oxide can increase its contact area with other materials, making it easier to exert its performance. Regarding the preparation method of flaky magnesium oxide, various reports basically first use a precipitation method to prepare a flaky magnesium hydroxide precursor, and then undergo a calcination treatment to obtain flaky magnesium oxide.
3. Magnesium oxide whiskers
Hebei Messi Biology Co., Ltd. stated that whiskers are needle-shaped or fibrous crystals with extremely small diameters and very small defects. The performance indicators of whiskers mainly include: whisker size, whisker strength, whisker surface chemistry, etc. As a new multi-functional inorganic material, magnesium oxide whiskers have good heat resistance, insulation, alkali resistance, stability and reinforcing properties. They can be used with resin, cement, etc., and are excellent reinforcing materials. At the same time, it can also be used as an adsorbent, thermal insulation material, sound-absorbing material, corrosion-resistant material, flame-retardant material, and thickener and reinforcing agent of unsaturated polyester. It has many and wide uses.
