Title:
SINTERED COMPACT OF COMPOUND OF ZINC, ANTIMONY AND CADMIUM AND ITS MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP3704557
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a sintered compact of a compound represented by chemical formula β-(Zn1-xCdx)4Sb3 in which residual stress is decreased and no crack is present and mechanical strength is increased and also to provide its manufacturing method.
SOLUTION: The sintered compact of a compound represented by chemical formula β-(Zn1-xCdx)4Sb3 can be obtained by preparing powder for forming a compound made up of a combination of Zn, Cd and Sb components in a proportion represented by β-(Zn1-xCdx)4Sb3 (where the symbol x is 0 to 0.3, excluding 0) by mole ratio, vacuum-sealing the powder, performing melting at about 650 to 700°C and solidification, crushing the resultant compound, successively maintaining the compound under the prescribed conditions of 50 to 100 MPa pressure and 400 to 500°C sintering temperature to carry out densification treatment and then releasing, after the completion of the treatment, the above pressure by the time the temperature reaches 95% of the sintering temperature. Its manufacturing method can also be provided.
