ABSTRACT:
A method for plastic working of ceramics comprising the steps of causing a sintered or pre-sintered body of polycrystalline ceramics containing at 20.degree. C. tetragonal-phase zirconia crystals to undergo plastic deformation at a temperature of about 1,000.degree. C. to about 1,600.degree. C. and then heating the ceramics body at a temperature of about 1,300.degree. C. to about 1,650.degree. C.
