Similar to the production of lime, magnesite can be burned in the presence of charcoal to produce MgO, which in the form of a mineral is known as periclase. Large quantities of magnesite are burnt to make magnesium oxide: an important refractory material used as a lining in blast furnaces, kilns, and incinerators. Calcination temperatures determine the reactivity of resulting oxide products and the classifications of light burnt and dead burnt refer to the surface area and resulting reactivity of the product, typically as determined by an industry metric of the iodine number. 'Light burnt' product generally refers to calcination commencing at 450 °C and proceeding to an upper limit of 900 °C - which results in good surface area and reactivity. Above 900 °C, the material loses its reactive crystalline structure and reverts to the chemically inert 'dead-burnt' product- which is preferred for use in refractory materials such as furnace linings. Magnesite can also be used as a binder in flooring material. Furthermore, it is being used as a catalyst and filler in the production of synthetic rubber and the preparation of magnesium chemicals and fertilizers.

Magnesium Carbonate Magnesite Powder MgCO3

Product descriptions from the supplier

Overview

Magnesium Carbonate

Character: In normal temperature, it’s with three hydrates. Light one is white, easily fragile or loose white powder. Odorless.

Relative density is 2.2. Melting point is 350℃. It’s stable in the air. When heated to 700℃, it will become magnesium oxide.

It’s hardly soluble in water, but it’ll bring a slight alkaline reaction.

It can not be soluble in ethanol but it could be soluble in olefine acid with sparkling.

Molecular Formula : xMgCO3·yMg(OH)2·zH2O      4MgCO3·Mg(OH)2·4H2O
CAS NO: 39409-82-0

Appearance : This product is a white granular powder, odourless, almost tasteless.
