EFFECT OF COOLING RATE ON TETRAGONAL (t) TO MONOCLINIC (m) TRANSITION IN HOT PRESSED ZrO_2(Zmol%Y_2O_3 CERAMIC
冷却速度对热压ZrO2（2mol%Y2O3）陶瓷中t→m转变的影响

The effeCt of cooling rate on transition from tetragonal (t) to monoclinic (m) structure in zirconia stabilized with Zmol% yttria is investigated by means of thermal expansion analysis and X-raydiffraction. Experimental results show that the volume fract
