Silica sand falls under the silicate group. Its chemical nomenclature is SiO2 better known as silicon di-oxide. The derivative of Silica is QUARTZ. Double decomposed form of silica is quartzite beside opal is yet another crystalline form. High quality crystal quartz, free from impurities or inclusions is commonly called a 'rock crystal' prized for its piezo-electric properties.

Graphite is a black to steel grey in color. It is one of the three allotropic forms of element carbon. It is found to occur in nature in three forms namely, flakes, crystalline and amorphous. The specific industrial application is very much dependent upon the form in which it is found to occur. The high refractoriness, good electrical & thermal conductivity, extreme softness & greasiness, water repellency & leaving a black smear on surface are the outstanding qualities for which it is valued in the industry.

Application

• Steel Industry
• Manufacturing of Pencils
• Batteries
• Paints
• Inks
• Brake & clutch lining
