Ceramic Industry
 Pyrophyllite is a relatively simple
compound of alumina and silica and, due to its physical properties, it is a raw material of superior quality which can be used in diverse industrial ceramic applications.
Newfoundland Pyrophyllite (ALTIFIL) has been used by American Olean for over 50 years in making a variety of products ranging from:
- wall and floor tiles
- sanitary ware,
- crockery and
- electrical porcelain.
Other applications include:
- Ceramic Glazes
- Contact Refractories for lining steel ladles
- Kiln Furniture for tunnel kilns
- Refractory Mortars
- Ingredients for Vitreous China, Stoneware and Chinaware
ALTIFIL is an ideal material for these applications since it:
- lowers the firing temperature
- suppresses deformation and cracking
- increases whiteness
- lowers firing shrinkage and
- improves thermal shock resistance
With ALTIFIL, you too can utilize a BRIGHTER source of Pyrophyllite both in the glaze and tile body.
Below you can find a typical Specification for whiteware/ceramic ALTIFIL.
