SYNTHESIS OF TiC-Ah03 NANOCOMPOSITE FROM IMPURE Ti0 2 BY MECI-IANICAL ACTIVATED SINTERING

In this research. the production possibility of TiC-: l. lz0 3 nunocornposite, as a usefu l ceramic from commercially pure TiOl • aluminum powder and carbon black has been investigated. Routile (TiOc) with carbon black and aluminum were placed in a high energy ball mill and sampled juring diff erent milling times. TI en, the activated powders were synthesized at different temperatures in an atmosphere control tube fu rn ace. Our results show that using this method has decreased the synthesizing temperature to 1000- 1250 C by increasi19 the milling. time. Also the width of X-ray patterns peaks. had made it apparent tl at, the size of produced TiC crystals vas ill order of nanometer, Furthermore it was detected that tilc lattice parameter deviated slightly from the standard size.
