These equipments all have the disadvantage of slow heating rate. For ordinary high-temperature box-type electric furnaces, it is difficult to control the atmosphere. Although the tube-type high-temperature furnace can control the atmosphere well, its heating rate is slow and has not yet reached the ideal level. Unnecessary reactions may occur before the reaction temperature to produce intermediates, thereby affecting the experimental results.
且上述两种设备因为有密封的加热体和保温层的覆盖，在制备过程中无法直观地看到装有反应试剂的坩埚的受热情况，因为坩埚的受热与加热体的距离有关，也会产生受热不均匀的问题。Moreover, because the above two devices are covered by a sealed heating body and an insulating layer, it is impossible to visually see the heating of the crucible containing the reaction reagents during the preparation process, because the heating of the crucible is related to the distance from the heating body. The problem of uneven heating.
