Experimental and analytical studies on fracture toughness of alumina ceramics were carried out, and the following results and conclusions were obtained.<br>(1) The fracture toughness obtained by conventional fracture mechanics approach is apparent one, and increases with an increase of precrack length and shows a constant value in the range of larger crack length.<br>(2) This characteristics was explained by the interaction between a main precrack and inherent microcracks or voids near the crack tip.<br>(3) The microcrack is often induced near the tip of the notch during cutting under green sheet. The microcrack results in the deviation from the linear relation between load versus displacement, and decreases the fracture toughness.<br>(4) If we avoid the elimination of factors (2) and (3) would enhance the fracture toughness and decrease its scatter.
