Methods of Electrical Field/Current Assisted Sintering

Chemické listy, 2022
Electrical current activated sintering is generally faster and requires lower temperatures than conventional sintering. This makes sintering significantly less energy intensive, especially for high temperature materials. Electrical current activated sintering methods are also useful for preparing materials which have unusual compositions or specific ...
