What Is Porcelain And How Is It Made
One of the key phases in the manufacture of porcelain is the in situ formation of mullite(2). Mullite is an aluminosilie material and depending on stoichiometry, has the formula 3Al 2 O 3 2SiO 2 and 2Al 2 O 3 SiO is a very rare mineral in the ground, but it is understood to form at around 1,100 °C from feldspar and kaolin type materials during the kiln firing process.
