Its main component is silica, 50-60% (by weight), but it also has appreciable levels of other oxides, often present in minerals found in traditional ceramic feedstocks such as aluminum oxide, calcium oxide and iron oxide and may contain other minor oxides and very small amounts of metals and alloys.
