The difference between high purity magnesia and light burned magnesium powder

Sintered magnesite is mainly composed of magnesite, hydromagnesite or magnesium hydroxide extracted from seawater by high temperature calcination. Strong resistance to hydration. Magnesite is calcined at 700-950 ℃ to escape CO2, and the resulting magnesite is a soft porous loose substance and cannot be used for refractory materials. Magnesite calcined at 1550-1600 ℃ is called sintered magnesite. With shaft kiln, rotary kiln and other high-temperature equipment one-time calcination or two-step calcination process, natural magnesite as raw material firing of burned magnesia called sintered magnesia

Light burned magnesium powder is a bending, pressure, high strength, gas hard, cementitious material, widely used in national defense, medicine, chemical industry, papermaking, shipbuilding and other industries. In the building materials industry can be made of tire board, particleboard, insulation column, railing, artificial marble, asbestos tile, ordinary tile, wallboard, laying the ground. With the progress of science and technology, the use of light burned magnesium powder is more extensive. It can be used as civil products, light and heavy mechanical packaging boxes, packaging bottom beams, high-temperature refractory materials, and can also produce beautiful and elegant furniture with strong gloss. Casting model can be done in the machinery industry.

The higher the purity of high-purity magnesia, the less the binding phase, the more unstable, and it is not necessarily suitable for refractory materials.

Magnesium olive sand small series from the market demand point of view of high purity magnesia

What is the market demand for magnesia with MgO ≥ 98%? The variety structure of refractory raw materials should be in line with the demand structure of the raw material market, in terms of steelmaking converter demand, except for products produced by high-purity magnesia with MgO ≥ 98% at the trunnion and slag line on both sides of the converter. Refractory products produced in other regions without high-purity magnesia are produced through light-fired kilns, magnesite ores, and coal combustion to produce gas through high-temperature calcination. Application fields of magnesium oxide: magnesium oxide

High purity magnesia is the choice of special. Grade magnesite ore, lightly burned, finely ground, dry press ball, super. High temperature oil shaft kiln sintering. The MgO content is more than 97%, the impurity content is low, the crystal is directly combined, and the structure is dense. is the production of high. Ideal raw material for grade alkaline bricks. Preparation of magnesite hot separation and certain re-election. Light burned magnesium has high activity and is an ideal raw material for the production of high body density magnesia. The main production of cementitious materials, but also do ceramic raw materials. After the light burned magnesium is chemically treated, it can be made into a variety of magnesium salts, which are used as raw materials for medicine, rubber, man-made fibers, and papermaking. The reburning magnesite products are mainly made of magnesite sintered in a high-temperature shaft kiln. High MgO content, usually between 90 and 93%, is the raw material for the production of ordinary magnesia bricks and unshaped refractories
