Simple sintering attachment for rapidly sintering block materials at an ultrahigh temperature

The invention provides a simple sintering attachment for rapidly sintering block materials at an ultrahigh temperature, comprising a jacket, a base, an upper cover, a thermocouple, an infrared thermometer and a graphite mold. A bottom cover is installed at the bottom of the jacket, the graphite mold is installed in a hollow cavity arranged by the jacket, the upper cover is installed at the top of the graphite mold, and the jacket is provided with a small hole for inserting the thermocouple as well as a temperature measurement window for the infrared thermometer at its side wall. In the light of the problems of complex mold and hollow cavity, high device and operation costs and high power consumption existing in rapid sintering of block materials with nanostructures in the prior art, the sintering attachment suitable for rapidly sintering nanometer block materials at an ultrahigh temperature in the invention can be used at a temperature of below 2500 DEG C, without the need for a vacuum cavity, a vacuum pump,
