talc | Definition, Uses, & Facts | Britannica
talc, common silicate mineral that is distinguished from almost all other minerals by its extreme softness (it has the lowest rating [1] on the Mohs scale of hardness) Its soapy or greasy feel accounts for the name soapstone given to compact aggregates of talc and other rockforming minerals Dense aggregates of highpurity talc are called steatite Since ancient times,Talc is the softest mineral with a Mohs hardness of 1 Its surface is rather hydrophobic; active hydroxy groups can be found only on broken edges and surfaces, thus the surface treatment of the filler is difficult It reinforces polymers due to its plateletlike geometry and has a strong nucleation effect in some crystalline polymers, furtherTalc an overview | ScienceDirect Topics

Dissolution rates of talc as a function of solution
Lin and Cemency (1981) measured the dissolution behavior of talc at 25 °C and pH ∼ 5 in a closedsystem reactor They observed that Mg from octahedral sheets was released more rapidly than Si from tetrahedral sheets, and suggested that talc dissolution rates are controlled by the destruction of these tetrahedral silica sheetsIntroduction of Talc Grinding Mill Clirik HGM Series talc grinding mill is widely used for micron powder producing The output size can reach 3000 mesh It is suitable to grind the material with middle and low hardness, moisture below 6%, and the material should be nonexplosive and nonflammable, such as: calcite, chalk, limestone, dolomiteGrinding Mill
(PDF) An Experimental Study of the Formation of Talc
The formation of talc from dolomite and silicarich fluid occurs at low temperatures in the metamorphism of the CaO–MgO–SiO 2 –CO 2In addition, for the two crosshead speeds, the introduction of the talc filler significantly increased the Young's modulus of neat PP However, the presence of talc increased the tensile yield stress of neat PP at the lower rate (1 mm/min), but decreased the tensile yield stress at the higher rate (50 mm/min) When the talc was mixed with PPEffect of talc content on the degradation of re
