Introduction. Pyrophyllite 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, …

Statewise production of pyrophyllite during 2017-18 to 2019-20 is furnished in Table-2. USES AND SPECIFICATIONS Pyrophyllite is harder than talc. Unlike talc, pyrophyllite does not flux when subjected to fire and maintains its strength after heating. It is, therefore, used in high-grade ceramic products, electric insulators and refractories.
