• Description:
  The U.S. Bureau of Mines investigated the synthesis of advanced ceramics (SiC+AIN, SiAION, SiC+Al2O3, and Si3N4+AIN) from natural clays (kaolin, halloysite, or montmorillonite) by an intercalation and heat treatment method. This process includes the steps of refining a clay, intercalating organic chemicals into its layered structure, drying the intercalated mixture, firing the treated structure at certain temperature ranges in controlled atmospheres to form desired compounds, and grinding the loosely agglomerated structure. Focus on this research is to economically process advanced ceramic structres from abundant natural resources. The advanced ceramic phases produced in this simple treatment are homogeneously distributed at the nanostructure level, and may potentially lead to cost effective manufacturing processes. The intercalation of clay was confirmed by X-ray and BET analyses. [Description provided by NIOSH]
