High temperature accessory is experimental equipment used for sample analysis in high temperature environment, in order to understand the changes in crystal structure of samples during high temperature heating and the changes in mutual dissolution of various substances during high temperature heating. According to different experimental requirements, different configurations of  high temperature attachment can be selected, such as different window materials and reaction chamber designs, to adapt to specific experimental conditions. High temperature attachment is indispensable temperature accessory in laboratory research, which not only improve the efficiency and accuracy of experiments, but also expand the boundaries of scientific research.
