A glass-bonded ceramic material from chrysotile (white asbestos)

  • K. J. D. Mackenzie

A process has been developed for bonding chrysotile asbestos into a robust, dimensionally-stable lightweight ceramic material by fusing it with sodium silicate and/or ground waste glass. The chrysotile can retain its desirable properties of fibrous morphology and porosity, but the fibre bundles are stabilized by fusion into a glassy matrix, reducing the respirable fibre concentration. The glass-bonded materials have good resistance to mechanical abrasion, and any resulting dust is found by SEM to be particularly free of fibres. The thermal treatment also converts the chrysotile into crystalline forsterite, which should destroy its cell toxicity. Other methods of glass-bonding chrysotile compacts (hot pressing and impregnating with glaze) were also investigated, and the properties of the resulting materials are reported.
