Q - Foundry Additives Glossary

Is widely deposited and is the most common variety of the min­eral, silica ( SiO2). Most quartz deposits contain impurities. It usually crystallizes in hexagonal prisms, or hexagonal pyramids. Its specific gravity is 2.65. It has a Moh's hardness of 7. Quartz is so widely used in the foundry that it is a basic aggregate.

Is a massive group of quartz grains cemented together by water, silica gel, and pressure. Most quartzites contain angular grains of silica. Quartzite is said to have been derived from sandstones under intense metamorphism. It is a refractory, as it has a melting point of 3092°F. (1700°C.) when it is in the pure state. Foreign contaminants lower its refractory value and its commercial foundry value. It is widely used in the foundry industry, not only for the base sand in molding and core making, but for various refractory purposes in lining furnaces, ladles and other uses.
