34. Hot compacting of ceramics
• The popular ways for production of P/M components are by cold or hot compact
ion, isostatic pressing and metal injection moulding. However, recently warm co
mpaction was reported as an innovative process that can attain high strength an
d high density compared to the existing methods. The elevated temperature of p
owder at moderate value of 150 o C offers high performance in material properti
es and economic advantages.
