"... form[s]... one of the major areas of materials science. ...Inorganic chemistry concerns basic molecules such as s, metals, s, and minerals. ...[M]ost of the raw materials for geopolymer synthesis are rock-forming minerals. ...There are numerous reasons for being interested in mineral polymers, more specifically in geopolymers. One is to get fire and heat properties that cannot be covered by organic materials. Another is the bridge... between polymer science and ceramics."
