Refractory ceramics must have a particularly high alumina content The phase line diagram of SiO 2 Al 2 O 3 has its highest point theoretically at 100% Al 2 O 3 and 2022°C thus minerals such as bauxite with higher Al 2 O 3 content than kaolinite has are added to natural kaolin to obtain the most refractory products Earthenware wall tile sanitary ware stoneware porcelain
