Quamvis mullite existat in minerali naturali, tamen eventus in natura rarissimi sunt.
Industria nititur mullis syntheticis, quae liquescentes vel 'calcando' varias alumino-silicates obtinent, ut kaolin, argilla, raro andalusita vel tenuis silica et alumina ad altas temperaturas.
Optimus fontes naturales mullorum est kaolin (sicut creta kaolinic). Optima est ad refractorias producendas sicut laterum accensorum vel non ignitorum, castariorum et plasticorum permixtus.
Mullite et mullite mixta principaliter adhibentur ad refractoria producenda et admixtionum ferro et titanium dejectiones.
