Chlorite and Chlorite-Rich Talcs in Cordierite

摘要

Since its discovery by the French geologist Cordier in 1913, cordierite has been the subject of extensive scientific investigation. It is produced industrially for a wide range of applications requiring materials with high thermal shock resistance. The Luzenac group has been supplying chlorite-rich talcs and chlorite to the mullite/cordierite kiln refractories industry for many years. The aim of this paper is to present the results of recent research for the purpose of comparing the action of pure chlorite (Sierralite) from the Antler deposit (Montana, USA) and chlorite-rich talc (50 wt-% chlorite content) from Europe's Trimouns (Luzenac 2C) and Rabenwald (Luzenac Naintsch HK70) deposits.
