specific Embodiment approach 1

[0006] Specific Embodiment 1: This embodiment is described in conjunction with FIG. 1 . The microwave sintering material holding device of this embodiment is composed of a glass vessel 1 with a cover, a heat-resistant material 2 and a corundum crucible 3; wherein the glass vessel 1 is filled with resistant The thermal material 2, the corundum crucible 3 is embedded in the heat-resistant material 2, and the thickness of the heat-resistant material 2 between the corundum crucible 3 and the glass vessel 1 is not less than 2cm.

[0007] The microwave sintering charging device of this embodiment greatly prolongs the service life of the corundum crucible, and the corundum crucible can be used repeatedly for more than 20 times.

specific Embodiment approach 2

[0008] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the glass vessel 1 is a quartz glass vessel. Others are the same as the first embodiment.

[0009] The high temperature resistance of quartz glass is better than ordinary glass.

specific Embodiment approach 3

[0010] Embodiment 3: The difference between this embodiment and Embodiment 1 is that the heat-resistant material 2 is mullite powder, corundum powder or zirconia powder. Others are the same as the first embodiment.

[0011] The heat-resistant material 2 of this embodiment has the advantages of high temperature resistance and good wave permeability. Even if the glassware 1 breaks due to other reasons, the heat-resistant material 2 of this embodiment will not burn, which ensures the sustainable progress of the reaction.

Abstract

A microwave sinter material container is formed by a glass container 1 with a cover, a flameproof material 2 and a diamond pot 3, for resolving the problems as non-uniform heating and acute temperature change. The glass container 1 contains the flameproof material 2, the diamond pot 3 is embedded in the material 2, and the thickness of the material 2 is not lower than 2cm, therefore, the invention can quickly heat and save energy, and heat uniformly to prolong the service life of diamond pot.

Description

technical field [0001] The invention relates to a material holding device. Background technique [0002] Since the microwave synthesis technology has the advantages of fast heating speed, energy saving and high efficiency, its application in the heating synthesis of solid materials has attracted people's attention since the 1990s. The price of the multi-cavity heating microwave oven is low, which is about one-fiftieth of the price of the microwave sintering furnace, so it is widely used. However, the heating of the multi-cavity heating microwave oven is uneven, and the pulse heating causes the crucible containing the material to be easily broken during the high-temperature synthesis of solid materials, which affects the experiment, and even makes the experiment impossible. For example, in the process of preparing long afterglow materials in the multi-cavity heating microwave oven, a small corundum crucible is loaded into a large corundum crucible, the material is put into a...
