    The values of γ LW for talc and pyrophyllite ( and mJ/m 2) are slightly smaller than for smectite clay minerals (e.g., the value for hectorite is mJ/m 2), the electron donor parameter values are roughly comparable for talc and pyrophyllite (γ ⊕ = and mJ/m 2) as are the values of the electron acceptor parameter (γ Cited by: Pyrophyllite is found in three main forms, fine-grained foliated lamellae with platy cleavage; radiating granular larger crystals and needles; and massive compact spherulitic aggregates of smaller crystals. It can be distinguished from talc and muscovite by its higher 2V, and from kaolinite, which has lower birefringence.

Pyrophyllite is a low expansion mineral. The individual particles expand less on heating (and therefore contract less on cooling) than other refractory particles (like silica). Thus, during firing, pyrophyllite particles counter the shrinkage of the plastic components surrounding them (assuming that particles remain whole and undissolved to exert their influence on the .

Pyrophyllite and talc are "end-member" phyllosilicates because they have no net layer charge. They are worthy of study because they serve as idealized models for discussing other, more complex clay minerals.

Like the neutral clay minerals, natural pyrophyllite and talc have no need for counterions and consequently contain no. COVID Resources.

Talc and pyrophyllite cannot make mixed crystals because of large differences in ionic radii of magnesium and aluminum.

PYROPHYLLITE Safety Data Sheet 01/04/ EN (English US) SDS ID: SIP 2/6 First-aid measures after skin contact: Wash with plenty of soap and water. Get medical advice/attention. First-aid measures after eye contact: Immediately flush eyes thoroughly with water for at least 15 minutes.

Remove contact lenses, if present and easy to do. Pyrophyllite occurs as fine-grain masses in the Ural mountains, Switzerland (Zermatt), South Africa, Canada and the U.S. (North Carolina, Georgia, California). The pearly white, yellow or green mineral can be difficult to distinguish visually from talc.

Pyrophyllite was carved by the ancient Chinese into small figurines and ornaments. Mice that received a sterile sc injection of talc were studied by measuring the incorporation of radioactive leucine and glucosamine into liver and plasma protein and the talc gramuloma at various intervals between 2 and hours after injection.

Incorporation into plasma proteins indicated a biphasic response with a marked increased incorporation into the perchloric acid.
