About Silica Powder

Silica Powder is a fine granular or amorphous powder with a density of 2.65 g/cm3 and a purity of 99.5% or higher. It is classified as an industrial grade product and is commonly known as Quartz Flour or Fumed Silica. This odorless and tasteless powder is composed of Silicon Dioxide (SiO2) and is insoluble in water but soluble in hydrofluoric acid. With a neutral pH level of 6.5 - 7.5, Silica Powder is widely used in fillers, sealants, coatings, and rubber reinforcement due to its high refractive rate of 1.46. It has a melting point of 1710C and does not boil but sublimates at 2950C. This inorganic compound conforms to ISO 3262 standards and is commonly stored in dry, well-ventilated areas away from moisture.
