preparation example Construction

[0033] Specifically, the preparation method of the titanium-aluminum-carbon material that can be etched in water of the present invention comprises the following steps:

[0034] In the first step, the raw materials used are Ti powder (99.9%), Al powder (98.9%), TiC powder (99.9%), and the powders of A-site doping elements are Si powder, Ga powder, Ge powder, In powder and Sn powder One or more of them; pure Ga powder (99.9%), In powder (99.9%) and Sn powder (99.9%) are preferred. The raw materials are all reagents from Aladdin Company. TiC as the preparation of Ti 3 AlC 2 It is a low-temperature additive for materials, which will reduce the temperature of phase formation; Al powder and powder of A-site doping elements are used to synthesize low-temperature soluble aluminum alloy raw materials, and must be kept at low temperature during sintering to generate soluble aluminum alloys. Instead of pure Al atomic layer.

[0035] In the second step, the Ti powder, Al powder, and ...

Embodiment 1

[0041] In the glove box, grind Ti powder, Al powder, TiC powder, Ga powder, In powder and Sn powder to obtain a uniformly mixed raw material. The molar ratio of Ti powder, Al powder and TiC powder is 3:1.2:2, with Based on the total mass of Al powder and A-site doping element powder, the percentage content of each component is: Al powder 90%, Sn powder 6%, Ga powder 2%, In powder 2%; graphite in spark plasma sintering furnace The inside of the mold is lined with a layer of graphite paper. Take 5g of the raw material mixed uniformly with an agate mortar and ball mill in the glove box and put it into the graphite mold. In the spark plasma sintering furnace, under vacuum conditions, apply an axial pressure of 10MPa. The heating rate is 100°C / min, hold at 700°C for 5 minutes, and hold at 1200°C for 5 minutes to obtain the required titanium-aluminum-carbon ceramic block that can be etched in water, and put the obtained ceramic block into Al 2 o 3 Add an appropriate amount of agate...

Abstract

The invention provides a titanium-aluminum-carbon material allowing underwater etching, a preparation method thereof, and a preparation method of an organ-shaped material. The preparation method of the titanium-aluminum-carbon material comprises the steps that (1) mixing and milling Ti powder, Al powder, TiC powder and powder of A-site doped elements to obtain a mixture, wherein the powder of theA-site doped elements is one or more of Si powder, Ga powder, Ge powder, In powder and Sn powder; 2) sintering the mixture to obtain a bulk raw material; 3) carrying out wet ball milling on the bulk raw material to obtain slurry; and 4) drying the slurry to obtain the titanium-aluminum-carbon powder material. The preparation method of the organ-shaped material comprises the following steps: placing a titanium-aluminum-carbon material into water and performing a reaction for 24-48 hours at 30-60 DEG C under a stirring condition to obtain the organ-shaped Ti3C2Tx material. The titanium-aluminum-carbon material can generate the organ-shaped Ti3C2Tx material through etching only by being put into water, so that the influence of solutions such as acid, alkali and the like on the environment iseffectively avoided.

Description

technical field [0001] The invention belongs to the field of preparation of MAX phase materials, in particular to a titanium aluminum carbon material which can be etched in water and its preparation method and organ-shaped Ti 3 C 2 T x The method of preparation of the material. Background technique [0002] In recent years, new three-dimensional layered materials M n+1 AX n It has received special attention from everyone, where M represents transition metals, such as V, Ti, Mo, etc., A is mainly group III or IV elements, such as Al, Ga, In, Sn, Si, etc., X is C or N, n=1 , 2, 3, 4, and 5 can be referred to as 211-phase, 312-phase, 413-phase and 523-phase respectively. And 312 phase Ti 3 AlC 2 This material is favored by everyone. Since the Ti-Al bond and the Al atomic layer are combined with metal bonds, the interlayer bonding method is similar to the van der Waals bond between graphite layers, so the Al atomic layer is easy to be bonded. Acidic or alkaline solution ...
