Description

technical field [0001] The invention relates to a heat-insulating and rotating integrated loading device. Background technique [0002] The main function of the sample stage under high temperature conditions is to be able to withstand high temperature and maintain the level of the sample, to support the sample material under high temperature conditions, and to realize the integration of high-efficiency heat insulation and loading, and to achieve high temperature within a limited short distance The isolation from the environment to normal temperature; at the same time, it is required to be able to realize the sealing function. Traditional high-temperature test benches use alumina or zirconia as heat-insulating materials, but limited by the melting point and mechanical strength of heat-insulating materials such as alumina, the measurement temperature of high-temperature measurement chambers is generally lower than 1800°C, which limits all The temperature range over which the ...
