  Thermal purifiion of natural mineral carbons

  Mineral graphite is resistant to attack by ordinary chemical agents, and has high melting and vaporization points. It is, therefore, useful for example as an ingredient in facing materials for foundries. Unlike most natural minerals, graphite is soft and unctious and, therefore, may be used as a lubricant either dry, or in oil or waterbased suspension. It is also used as an .
