The boundary of the change process of electrode paste during sintering is not very obvious, but in order to facilitate research and control, according to the temperature and position of sintering, it can be roughly divided into three stages:
(1) Softening stage. The temperature rises from 25 degrees to 120-200. It is roughly 50cm above the electric jaw.
(2) The volatilization stage. The temperature rises from 120-200 to 650-750, roughly in the half-ring position.
(3) The sintering stage. The temperature rose from 650-750 to 900-1000.
