Abstract
A method for preparation of zirconia toughened mullite using DC plasma is p resented. An indigenously developed 50 kW thermal plasma reactor is used fo r preparation of zirconia toughened mullite (ZTM) from premixed zircon and alumina mixture. ZTM of different compositions were prepared by varying alu mina content in the mixture. Finer grain size (< 1 mu m) of zirconia is obs erved in aluminium-rich mullite compared to that of the silicon-rich mullit e. (C) 2000 Elsevier Science B.V. All rights reserved.
