摘要： Fine-grained material is heat treated by being preheated and then is heated to its calcining or sintering temperature, following which it is again heated to such temperature and subsequently cooled. The concentration and residence time of the material during its second heating are greater than they are during its first heating, and the concentration of oxygen is greater during the first heating of the material than during its second heating.
