Magnesium oxide is an ionic compound composed of magnesium element and oxygen element, belonging to alkaline oxide. Commonly known as bitter soil, also known as magnesium oxide. Chemical MgO is highly fire-resistant and insulating, slightly soluble in water, placed in the air, easy to absorb water and gas and gradually become basic magnesium carbonate. Therefore, before and after use, during transportation, it should be sealed and stored in a dry and ventilated environment.

Magnesium oxide is an important material in many fields although it is not often contacted in our life.

In the chemical industry, magnesium oxide is the raw material for producing other chemical products. In the construction industry, it can be used to manufacture artificial chemical floors, artificial marble heat shields, sound insulation panels, plastics, etc. It can be used as a standard for white pigments. It can be used for the determination of coal. In addition, magnesium oxide can be used as a flame retardant, which is a traditional flame retardant material.

Magnesium oxide has a wide range of uses and varieties.

Generally, magnesium oxide can be divided into heavy magnesium oxide and light magnesium oxide. Heavy magnesium oxide can be divided into heavy burning powder and light burning powder according to different burning intensity, and light burning powder can be divided into building materials powder and desulfurization powder.

Light magnesium oxide is a chemical product with white color, high content and fluffy volume. The appearance is white amorphous powder.

Heavy magnesium oxide is the product of ore burning, compact in volume, white or beige powder. It is easy to combine with water and absorb moisture when placed in the air. It is easy to gel and harden when mixed with magnesium chloride solution.

Light magnesium oxide and heavy magnesium oxide have different application fields.

Light magnesium oxide is mainly used in the production of rubber products and neoprene adhesive. In rubber manufacturing, magnesium oxide acts as an acid absorbent and accelerator, and in ceramics and enamel, it plays a role in reducing the sintering temperature. It can be used as filler in the manufacture of grinding wheel and paint, as whitening agent or refined decolorizing agent of granulated sugar in food processing, and as fertilizer and feed additive for livestock in agriculture

Heavy magnesium oxide can be used in the chemical industry to produce magnesium salt, in the building industry to manufacture artificial chemical floor, artificial marble heat shield, sound insulation board, and in the plastic industry as filler.

On behalf of provincial civil-military product enterprises, the company participated in the Exhibition of Civil-Military Integration Development Achievements of Science, Technology and Industry for National Defense

Our company is honored as a public service platform for civil-military integration

China Civil-Military Technology Application Competition (hereinafter referred to as “the competition”) has been held for two consecutive sessions. The vast number of civil-military enterprises in Hebei Province actively participated in the competition, and a total of 13 projects have won awards. Among them, Tangshan Weihao Magnesium Powder Co., Ltd. participated in the competition with the project “Preparation of high-purity spheroidized series magnesium alloy powder materials”, and won the bronze award in the second session of the competition.

The production method and device of high-purity atomized spherical magnesium alloy powder were awarded the patent for invention

Through the unremitting efforts of the R&D team of Tangshan Weihao Magnesium Powder Co., Ltd., on the basis of its own patent for invention of atomized magnesium powder, another major technological breakthrough has been achieved, in which a new product of nanocrystalline high-purity atomized spherical magnesium alloy powder was developed. The particle size range of the product was further improved. The size of nanocrystals mainly ranges from 100 to 3000nm, with concentrated distribution, active metal content greater than 98.5%, and the sphericity greater than 95%. The room temperature mechanical properties of the components prepared by high pressure forming and spark plasma sintering through AZ91 magnesium alloy powder in the series products (pressing temperature 250℃, sintering temperature 300℃) are as follows: Tensile strength 420MPa, yield strength 390Mpa, grain size of the components 100-300nm. The mechanical properties of the components prepared by the warm pressing sintering method through ZK61 magnesium alloy powder (temperature 300℃ and pressure load 1000KN) are as follows: Tensile strength 410 Mpa, yield strength 380 MPa, elongation rate 9.5%, and the grain size of the component ranging from 100 to 300nm. The mechanical properties of the components are better than that of ordinary atomized powder.
