Title:
ELECTRIC CONDUCTIVE ALUMINUM NITRIDE SINTERED COMPACT AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH05286767
Kind Code:
A
Abstract:
PURPOSE: To produce an aluminum nitride sintered compact capable of electric spark machining.
CONSTITUTION: Aluminum nitride (AlN) powder having ≤2μm average particle diameter is blended with titanium nitride (TiN) powder and /or zirconium nitride (ZrN) powder and powder of a compd. of a group IIIa element as a sintering aid and the resulting blend is sintered at 1,600-2,000°C in a nonoxidizing atmosphere to obtain the objective aluminum nitride sintered compact. This sintered compact has ≤1Ω.cm resistivity and can be subjected to electric spark machining.
