Silica Defined. Silica is another name for the chemical compound silicon dioxide. Each unit of silica includes one atom of silicon and two atoms of oxygen. If you have never heard of silica before, you might be surprised to hear that you probably come into contact with it every day.
Silica is silicon dioxide, and is the most common component of rocks. Different magmas have different amounts of silica in them. High silica magmas are extremely viscous and t â¦ end to erupt explosively.ilica is the mineral quartz (SiO2) and silicon is the element (Si) which is a major rock forming element in Earth's crust, and is therefore found nearly everywhere. Concentra â¦ tions of silica which are mined are usually in the form of quartz sand or sandstone deposits.
