Magnesium oxide (chemical formula: MgO) is an oxide of magnesium, an ionic compound. It is a white solid at room temperature. Magnesium oxide exists in the form of periclase in nature and is a raw material for magnesium smelting.
Magnesium oxide is commonly known as bitter soil, also known as magnesium oxide. Magnesium oxide is a basic oxide and has the property of a basic oxide. It is a gelling material. White powder (light yellow is magnesium nitride), odorless, tasteless, non-toxic, is a typical alkaline earth metal oxide, chemical formula MgO. A white powder having a melting point of 2852 ° C, a boiling point of 3600 ° C and a relative density of 3.58 (25 ° C). Soluble in acid and ammonium salt solution, insoluble in alcohol. Solubility in water is 0.00062 g/100 mL (0 °C)
Magnesium oxide has a high degree of refractory insulation properties. It can be converted into crystals by burning at a temperature above 1000 ° C. When it is raised to 1500 - 2000 ° C, it is formed into a burnt magnesia (also known as magnesia) or sintered magnesia.
Magnesium oxide is one of the magnesia chemical materials. Magnesium oxide is classified into light burned magnesia and reburned magnesia according to the calcination production process. The light burned magnesia currently used in the magnesite industry refers to magnesia formed by calcining the compound at 700-900 ° C, and also becomes active magnesium oxide, chemical formula MgO, relative molecular mass 40.30, melting point 2800 ° C, odorless It is odorless, non-toxic, insoluble in pure water and organic solvents. The solubility in water increases due to the presence of CO2 and can be dissolved in acid or ammonium salt solution. Easy to tide knot, can gradually absorb CO2 and water in the air to form magnesium carbonate double salt.
1: Fireproof board: Requirements for magnesium oxide: white color and high activity (in order to achieve non-halogenation of the export plate, the activity of magnesium oxide must be guaranteed to be above 60%). The requirement for the heat generation of magnesium oxide is not very high. Because the fire board is thin, the heat dissipation is faster.
2: Wallboard: The color requirement of magnesium oxide is not very high, the content is required, because the product to be made should be fully combined with magnesium chloride, and the strength of the wallboard is increased, and the grade is lower than that required by the fireproof board.
3: greenhouse bracket: magnesium oxide is relatively high, because the finished product of the greenhouse should have flexibility, strength, wind nuclear load, and must not return to the brine (if the brine returned to the farmland will be burned out Sapling
4: Composite duct: the requirements are not too high, mainly requiring the whiteness and strength of magnesium oxide. .
5: Magnesite manhole cover: Like the greenhouse bracket, because the volume is extremely large and thick, the content of magnesium oxide must be uniform and the activity should be good. The manhole cover made with the product with low activity will definitely show the phenomenon of returning halogen, deformation and bursting. !
6: movable room, magnesite tile: no color is required, the content is over 65, and the mesh is about 120 mesh.
7: Color tile: no color is required, but activity and content are required.
