The Pyrotrol group of mineral products offers a controlled blend of milled Andalusite/Pyrophyllite ores designed to control strinkage in whiteware ceramic applications. Pyrotrol reduces thermal expansion, stabilizes shrinkage, widens firing range and reduces warpage.
Alumina content is controlled to meet certain specifications. Pyrotrol produces an excellent kiln car wash and is an inexpensive coating material for facebrick production.
This material is dry milled and magnetically separated.
