Talc is a mineral widely used in the ceramic, paper, plastics, rubber, paint, and cosmetic industries. Four distinct forms of pulmonary disease caused by talc have been defined. Three of them (talcosilicosis, talcoasbestosis, and pure talcosis) are associated with aspiration and differ in the composition of the inhaled substance. The fourth form, a …

Talc, a layered magnesium silicate mineral with the ideal formula Mg 3 Si 4 O 10 (OH) 2, is used as filler in composite materials to reduce their production costs, improve their physical and chemical properties, and/or to offer new functionalities.It is used in a large number of industrial applications (most commonly in papers, paints, ceramics, …

Because all patients in this study were born before 1970, which was the time point when talc manufacturers claimed to voluntarily remove asbestos contamination from commercial talc preparations (establishing a cosmetic grade "free of asbestos" vs industrial grade that may contain it), 22, 23 and because these patients had talc exposure …

Talc will matte low temperature glazes, simply because it is stiffening the melt. Yet, at middle temperatures (e.g. cone 6) a small amount of talc (e.g. 2-4%) can greatly improve body maturity, several cones can be gained. However, if more …

The most popular talc alternatives are silica, zinc oxide and corn starch. Silica has seen the most search growth over the past four years. But smaller-volume talc-alternatives searches are showing relatively big jumps in interest, too. Both rice starch and tapioca starch had minimal searches in 2012 and now are biting the heels of the popular ...

Talc and 10-Å phase are hydrous phases that are implicated in fluid processes and rheological behaviour in subduction zones. Natural samples of talc show limited compositional variation away from the MgO–SiO2–H2O (MSH) endmember, with only substitution of Fe2+ for Mg occurring in significant amounts. In experiments at 2 GPa, …

The hydroxyl stretching frequencies of four phyllosilicates have been measured at high pressures and temperatures using an externally heated diamond-anvil cell and synchrotron infrared spectroscopy. Spectra were measured up to 26, 31, 21 and 8 GPa at room temperature for samples of talc, pyrophyllite, muscovite and 10-Å phase, …

Electrical conductivity of talc was measured at 0.5 GPa and ~473 to ~1,300 K by using impedance spectroscopy both before and after dehydration. Before dehydration, the electrical conductivity of talc increased with temperature and is ~10−4 S/m at 1,078 K. After dehydration, most of the talc changed to a mixture of enstatite and quartz and the …

The flotation separation of chalcopyrite and talc is challenging due to their similar natural floatability characteristics. Besides, it is usually difficult to effectively inhibit talc by adding sodium carboxymethyl cellulose (CMC) alone during chalcopyrite flotation. Here, a combined inhibitor comprising acidified sodium silicate (ASS) and CMC was …

Talc cleavage planes are near-uniformly aligned in the talc-actinolite schist, suggesting talc may have accommodated significant strain by frictional sliding along [001] (e.g., Moore & Lockner, 2008, Figure 3a). In contrast, the ability of chlorite to accommodate high strain appears to have been highly dependent on orientation and phase mixing.
