Abstract
The invention discloses a method for preparing porous titanium nitride ceramics, and belongs to the field of preparation of functional materials. The method for preparing the porous titanium nitride ceramics has the advantages that the porous titanium nitride ceramics are high in porosity and low in preparation cost; porous titanium nitride is mainly made of inexpensive titanium oxide powder and carbon black by the aid of the carbon thermal reduction method; raw materials of the porous titanium nitrite ceramics are inexpensive, the porous titanium nitride ceramics are low in production cost, and the porosity of the porous titanium nitride ceramics prepared by the aid of the method can reach 78.6%.
Description
Technical field
The invention belongs to functional materials preparation field, particularly relate to a kind of porous titanium nitride ceramic preparation.
Background technology
Titanium nitride ceramic is a kind of novel high-strength and refractory wear-resistant ceramic material, has excellent chemical stability and antioxidant property, and higher electroconductibility and superconduction critical temperature, is thus used widely.Titanium nitride ceramic coating can improve the wear resisting property of cutting tool, improves the work-ing life of cutting tool.Titanium nitride ceramic can also be applied to the chemical devices such as protective cover for thermocouple, heat exchanger.In addition, titanium nitride ceramic can be used as the material such as electrode and electrical contact of fused salt electrolysis.Titanium nitride porous ceramics is a kind of new ceramic material risen gradually on research titanium nitride ceramic and porous ceramics basis in recent years, because it gives full play to the excellent properties of titanium nitride and porous ceramics and noticeable, prepare the focus that the titanium nitride porous ceramics with high porosity is studied especially at present.
The preparation method of traditional titanium nitride porous ceramics material is based on direct nitridation method, by being that main raw material first makes POROUS TITANIUM with titanium valve, then in nitrogen, carry out nitrogenizing reaction prepare titanium nitride porous ceramics, the shortcoming of the method is in nitridation process, titanium valve surface can form the nitridation process that titanium nitride membrane seriously hinders titanium valve, titanium valve is caused to be difficult to complete nitrogenize, studies have found that and adopt the titanium valve of special processing to carry out nitrogenizing reaction, complete nitrogenize can be realized, but titanium valve needs special processing, add preparation cost.So direct nitridation method complex manufacturing, high cost, the titanium nitride porous ceramics purity of preparation is not high, is unfavorable for suitability for industrialized production.
Summary of the invention
The object of this invention is to provide the porous titanium nitride ceramic preparation that a kind of void content is high, preparation cost is low.
The present invention is achieved by the following technical programs: a kind of porous titanium nitride ceramic preparation, comprises the steps: TiO
2exhale for 1:2 in molar ratio with carbon black and, the powder prepared and abrading-ball are put into mixing tank, take dehydrated alcohol as medium planetary ball mill wet mixing 24h, after batch mixing, slip is put into loft drier dry, sieve with 200 object screen clothes again, powder is evenly put into mould, when not adding load, rely on the hammer deadweight press forming of pressing machine, obtain the rectangular parallelepiped sample of rule, sample is placed on and scribbles in the plumbago crucible of BN, then multifunctional furnace is put into, sinter under the nitrogen pressure of 0.5MPa, obtain porous titanium nitride pottery, sintering temperature is 1650 DEG C, sintering time is 2h, temperature-rise period is as follows: (1) starts heating, l0min post-heating to 300 DEG C, (2) heating is continued, 1h post-heating to 1200 DEG C, and at this temperature 5min, (3) 4h post-heating is to holding temperature, holding temperature 1650 DEG C, and soaking time is 2h, and temperature-rise period terminates, and wherein, starts to pass into N 1200 DEG C time
2, flow is 16L/h, and keeps nitrogen pressure in furnace to be close N after 0.5MPa, 1h
2.
The present invention has following beneficial effect:
The method prepares porous titanium nitride with the titanium dioxide powder of cheapness, carbon black for main raw material, and production cost is low, and the void content of the porous titanium nitride pottery prepared is up to 78.6%.
Embodiment
