example 1

[0038] Weigh 20 unit weight (for example, kilogram) of NaCl-KCl eutectic salt, and mix it with 1.2 unit weight of Ti powder, 0.23 unit weight of Al powder, and 0.2 unit weight of nano-C powder (average particle size 50nm). Place it in a corundum crucible. Place the crucible above in a stainless steel reactor, seal it and protect it with Ar gas. Use a temperature controller to heat up to 900°C at a rate of 5°C / min, keep it at this temperature for 2h, and then cool down to room temperature with the furnace after power off. The obtained product is taken out, rinsed with deionized water to remove residual molten salt, and then dried at low temperature to obtain the target product.

[0039] Test the obtained target product, and its XRD pattern, SEM and TEM photos are as follows: figure 2 , 3 And shown in 4. by figure 2 It can be seen that the obtained nano powder is Ti 3 AlC 2 , After further testing, the resultant product contains Ti 3 AlC 2 The particle size of the nano powder i...

Place the crucible above in a stainless steel reactor, seal it and protect it with Ar gas. Use a temperature controller to heat up to 950°C at a rate of 10°C / min, keep it at this temperature for 3h, and then cool down to room temperature with the furnace after power off. The obtained product is taken out, rinsed with deionized water to remove residual molten salt, and then dried at low temperature to obtain the target product.

Abstract

The invention provides a preparation method and an energy storage material of multiple conductive ceramic materials with layered structures. The method includes the steps: directly forming raw material mixture according to stoichiometric ratio; performing reaction on the raw material mixture in molten salt in inert atmosphere, and cooling the raw material mixture after reaction to obtain product mixture; removing the molten salt in the product mixture to obtain the multiple conductive ceramic materials with the layered structures. The structural formula of the multiple conductive ceramic materials is (M1-xYx)n+1ACn, wherein n=1, 2 or 3, 0<=x<=1, M and Y are transition metal elements, A is IIIA or IVA element with atomic number above 13, and C is carbon. The preparation method can solve oneor more of the problems of high synthesis temperature, complicated preparation technology and equipment, high cost and the like of existing multiple conductive ceramic materials. Moreover, the preparation method has the advantages of rapidness, high efficiency, energy conservation, environmental protection, low cost, easiness in implementation of large-scale production and the like.
