Abstract：
 A high-toughness alumina ceramics is prepared from Al(OH)3 and AlOOH through wet ball grinding with alpha-Al2O balls and deionized water, drying, calcining in muffle furnace, adding alcohol, ball grinding, shaping, vacuum high-pressure calcining. Its advantages are low cost, easy control of process and high toughness and strength of the ceramics.
