Listed Below are Some Uses of Burnt Rice Husk in Various industries:
- Steel industries- Due to the finest insulating properties of burnt rice husk it becomes quite easy to produce thermal insulating compound. Some of its great feature are high melting point, low thermal conductivity point, highly porous and thus its makes the ideal raw material for producing steel. Apart from this it could also be used like a coating over the molten metal. It also works as a very good insulator as it does not allow the metal to cool down quickly after smelting.
- Construction industries- Usually the blended cements are produced with the help of burnt rice husk.
