WhatsApp: +86 18221755073Pyrophyllite is an industrial mineral that is easily processable and has excellent thermal stability. Pyrophyllite is a hydrated silicate mineral containing Al 2 O 3 (>28.35 wt%), which has low hardness (1–2) that allows it to be readily ground into a powder. When pyrophyllite is heated to 1450–1480 °C it forms mullite and cristobalite, which increases the hardness to …
