Refractory Minerals and Pyrophyllite

Minerals for common brick and ceramics applications.

Piedmont Minerals is a division of Resco Products. It has been mining and processing a unique pyrophyllite and andalusite body of ore for over 60 years in Hillsborough, North Carolina. The white color is due to the low iron of this material. The slight expansion on firing has found a variety of uses in ceramic, brick, and refractory industries.

Several milled grades are available, as are crushed and screened grains. All grades are available in bulk, super sacks, and in 50lb bags.

Types of Pyrophyllite Refractory Minerals

Pyrotrol 2253 - Is a milled, low iron, 200 mesh pyrophyllite. Also available n pallet quantities from our Cedar Heights Clay facility in Oak Hill, Ohio. It is also available in less than pallet quantities from these distributors; L&R Specialties, Laguna Clay Company, Dakota Potter's Supply, and Kentucky Mudwords. Can help control fired shrinkage and fired toughness as a partial replacement for silica in ceramic bodies.

Alkatrol 20031 - Is a milled low iron pyrophyllite that also contains foliated sericite which raises the alkali level. Traditionally used to control shrinkage and thermal expansion in ceramic tile bodies. It is also an excellent base material for white coatings in the brick industry.
