Rice husk ash

We have two qualities in this segment: High carbon powder up to 5%. Low-carbon powder up to 1.5%. Up to 93% SiO2. Silicon dioxide (silica, Silicon dioxide, silica) is a substance consisting of crystals that have high strength, hardness and refractoriness. Silicon dioxide is resistant to acids and does not interact with water. When the reaction temperature increases, the substance interacts with alkalis, dissolves in hydrofluoric acid, and is an excellent dielectric. Natural silicon dioxide, called silica, is widely used in construction (concrete, sand, sound- and heat-insulating materials). Application of silicon dioxide: Silicon-containing materials are widely used both in the field of high technologies and in everyday life. Silicon dioxide is used in the production of glass, ceramics, concrete products, abrasive materials, as well as in radio equipment, ultrasonic devices, lighters, etc.
