The conductive end plate is embedded in the pyrophyllite ring. The lower periphery of the conductive steel ring is filled with a dolomite ring. The centers of the pyrophyllite ring, the dolomite ring, the conductive end plate and the conductive steel ring are on the same axis. The plug can effectively reduce the heat loss of the plug and ensure the temperature stability in the synthesis cavity, but there are still the following problems:

[0012] Compared with the prior art, the beneficial effects of the utility model are:
