Product Description
Also known as silicon dioxide, every unit of white Silica Powder contains two oxygen and single silicon atoms. It is naturally present in quartz mineral. It is used as one of the key ingredients of glass and sand. This mineral is known for its excellent hardness level. It tends to burn quickly when comes in contact with flame or heat. Water is not adequate to extinguish this powder.  This low toxin content based powder can integrate with different sorts of polymers and molecules. This mineral can withstand high temperature. It is burst protected and has excellent isolation properties.

Primarily, coke and silica are heated in electric furnace under extremely high temperature to promote chemical reaction. During this reaction, oxygen is eradicated so that silicon remains behind. After producing silicon, carbon atom is replaced.
