High-pressure etching of diamond in chloride melt in the presence of aqueous fluid.

The article focuses on a study that explores the etching of diamond crystals by chloride melt in the presence of aqueous fluid. It mentions that halide melts were experimentally tested as possible natural solvents of diamond at high pressure. It adds that experiments were performed on the multianvil high-pressure apparatus wherein etching of the diamonds were carried out in platinum ampoules. Results confirm that the presence of aqueous fluid on the chloride system under high pressures and temperatures has increased the rate of diamond etching, similar to silicate systems.
