| Abstract: | The static and dynamic temperature distribution in the well type two zone furnace are described. It is pointed out that the temperature T 1 of constant temperature terrace in high temperature zone, the temperature T 2 of that in lower temperature zone and the moving speed V are three essential technological factors. The skill of the adjustment of three essential factors and the results of the ceramic wafers are given. Second sintering technology using well type two zone furnace is also presented. By means of this technology, not only the highly difficultly sintered PTC semistors can be prepared, but also the properties of the wafers are improved. |
