Fast talc

Hydrated magnesium silicate, better known as talc, forms underground over geological time periods, but a rapid hydrothermal synthesis has been developed by researchers in France. Their approach could open new applications for a consistent, high-purity form of this material in paper making, plastic, paint and coatings, rubber, food, electric cable, pharmaceuticals, ceramics, and cosmetics. Angela Dumas and colleagues used supercritical water to speed their synthesis.
