It is divided into three categories: sintered magnesia, light burned magnesia, and fused magnesia.
Magnesia is one of the most important raw materials for refractories,
Used in the manufacture of various magnesia bricks, magnesia-aluminum bricks, ramming materials, furnace materials, etc.
Containing more impurities, it is used to pave the bottom of steelmaking furnaces, etc.
Light burned magnesia powder is a flexural, pressure-resistant, high-strength, air-hardened, and cementing material, which is widely used in defense, medicine, chemical, paper, shipbuilding and other industries. In the building materials industry, it can be made into carcass boards, particle boards, thermal insulation pillars, railings, artificial marble, asbestos tiles, ordinary tiles, wall panels, and paving the ground. With the advancement of technology, light-burned magnesia powder can be used in a wider range of applications. It can be used for civil engineering products, light and heavy machinery packaging boxes, packaging bottom beams, high-temperature refractory materials, and it can also produce beautiful and elegant furniture with strong gloss. It can be used in the machinery industry. Cast model.
Fused magnesia is made by fusing selected special A-grade natural magnesite or high-purity light-burned magnesia particles in an electric arc furnace. The product has high purity, large crystal grains, dense structure, strong slag resistance, and good thermal shock stability. It is an excellent high-temperature electrical insulation material, and it is also used to make high-grade magnesia bricks, magnesia carbon bricks and unshaped refractory materials. Important raw materials.
