Title:
LOW DENSITY MOLYBDENUM SINTERED COMPACT AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH10168505
Kind Code:
A
Abstract:
To provide a low density molybdenum sintered compact capable of inexpensively forming a low density and high strength product with a high purity, its production, and a product using the sintered compact.
The low density molybdenum sintered compact has ≥60kg/mm2 bending strength and 70-85% relative density. This low density molybdenum sintered compact can be produced by subjecting a coagulated powder of Mo to heat treatment at 1200-1800°C and then to crushing and subjecting the resultant coarse-grained Mo powder of 60-150μm grain size to pressing and then to sintering at 1800°C. The resultant sintered compact has a structure in which large pores 20 are present among the grains 10 of the coarse-grained Mo.
