ALTIFIL™ and ALTIPLUS™ products imparts strength to fired ceramic products and are used in ceramics for their excellent heat shock and creep resistance properties. Pyrophyllite is also used to manufacturer wall tiles, ceramic bodies, whiteware, vitreous china and stoneware.

Pyrophyllite goes through several thermal transformation phases when heated at different temperatures. Permanent expansion occurs from dehydration between 650-870°C, which corresponds to the greatest weight loss and the percentage of expansion on the particle size. When exposed to temperatures above 1100°C, a transformation to mullite corresponds to significant increases in all aspects of its mechanical properties: compression strength, chemical resistance, translucence, flexural strength and hardness. Due to its ability to heat quickly and convert to mullite at 1100°C, it allows faster firing cycles than similar materials. Functions include fluxing agent, frit, glazes and engobe properties, glaze body fit, mechanical properties and thermal shock resistance.

Applications include automotive ceramics, Corderite-mullite refractories, electro-ceramics, frits/glazes, floor and wall tile, large format tiles, white body tiles, thin tiles, porcelain tiles, sanitaryware and dinnerware.”


Pyrophyllite is a key component in commercial production of E-Glass fibers, which enables the elimination of sand in the batch and improves batch-to-melt conversion efficiency and lowers conversion energy.


Trinity offers a high brightness, high aspect ratio product that replaces talc as a reinforcing additive for strength.


Pyrophyllite’s presence in agriculture includes its use as an anti-caking agent and moisture barrier in feed pre-mixes, enhancing the flowability and effectiveness of agricultural products.


In ceramics, pyrophyllite is employed to manufacture high-temperature porcelain and whiteware, ensuring consistent and robust finished products in kiln firing processes.


Pyrophyllite’s versatility extends to the paint and coatings industry, where it acts as an extender and corrosion-resistant pigment, enhancing the performance of coatings and paints.
