Silica
"Silica is a compound of silicon and oxygen (SiO2) which are the most abundant elements found in the Earth's crust. Quartz is its most abundant type and is found in soil, sand and rocks. In cement production, silica combines with lime to produce clinker which is the base material for cement. Cement, when hardened, owes its strength to the products of the mixture of lime and silica."


Vital component for fiberboard manufacturing
Silica is also widely used in glass manufacturing, water treatment, paints and coatings industry, as well as electronics industry.
