Introduction of Brucite(Magnesium Hydroxide)

In industry, Magnesium Hydroxide(Brucite) powder is applied to neutralize acidic wastewaters as a non-hazardous alkali. It also could be  a part of building artificial reefs. Common uses of Magnesium Hydroxide as a fire retardant include plastics, roofing, and coatings. This is due to the endothermic decomposition it undergoes at 332 °C (630 °F):

Mg(OH)2 (s) → MgO (s) + H2O (g)

The heat absorbed by the reaction acts as a retardant by delaying ignition of the associated substance. The water released dilutes any combustible gases and inhibits oxygen from aiding the combustion.

In agriculture, Magnesium Hydroxide can be used in the acidic soil as well as sandy soil, which continuously provides crops, such as oil palm, orange, banana, etc with Magnesium.
