Abstract
The invention relates to a novel ceramic material and a preparation method thereof, belonging to the technical field of ceramic processing. The novel ceramic material is prepared from the following components in parts by weight: 60-85 parts of Al2O3, 20-40 parts of TiC, 5-10 parts of Co and 5-10 parts of Si3N4. The preparation method for the novel ceramic material comprises the following steps: mixing the components in proportion, ball-milling the components for 24 hours in an alcohol solution; then, performing hot-pressing and sintering for 1-2 hours at a temperature of 1600-1700 DEG C under the pressure of 25MPa in the presence of an Ar gas to obtain the novel ceramic. The ceramic material prepared by the preparation method is obviously improved in sintering process performance, mechanical performance, strength level, fracture toughness and wear resistance in comparison with the conventional ceramic.
Description
Technical field
The present invention relates to a kind of stupalith and preparation method thereof, be specifically related to a kind of new ceramic material and preparation method thereof, belong to ceramic processing technique field.
Background technology
Stupalith is the metallic substance that continues, most important one in the ceramic that after nonmetal macromolecular material, people pay close attention to, because it has the Common advantages of metal and macromolecular material concurrently simultaneously, in this external continuous modifying process, the very large improvement that made its easily cracked performance have.Therefore, its Application Areas and various product have a fairly obvious raising.As u.s.a. military affairs material experiment chief of the office R.Kaiz 21 century high performance ceramic material application one literary composition point out: the technology of preparing of advanced stupalith and application can be regarded us as and enter one of important symbol of 21 century industrial economy competitive power.
Traditional stupalith all comes from nature, therefore, the material made with them performance or all compare qualitatively be difficult to control.So a large amount of this kind of materials can only be used on daily necessities.As all kinds of pottery, porcelain and other daily necessities.Because traditional ceramics has certain resistance to chemical attack characteristic and higher resistivity, therefore parts of traditional pottery is applied to industry as chemical reaction container, pipeline and impregnating material, its major advantage is that fusing point is high, can be high temperature resistant, hardness is high, wear-resistant, chemical stability is high, do not corrode, lightweight, Young's modulus is large.But its main weakness is plastic deformation ability, easily brittle rupture and not easily machine-shaping occur, these reasons strongly limit industrially range of application.Application particularly in mechanical industry.And application on electrical equipment also primary limitation at high voltage electric porcelain vase and dielectric member etc. thereof in a few.
The new ceramic material that modern industry occurs, as subminiaturization, hypervelocity, ultrahigh-temperature, high pressure etc., has all kinds of stupaliths of excellent specific property as SiC, Si

3except being utilized as the electromagnetic materials such as photoconduction, superconduction, magnetic, more be used to other functional materials all kinds of, take full advantage of the chemistry of stupalith, heat and good mechanical property these people, as the fifties steam turbine the temperature of nozzle reach 800e, adopted alloy nozzle at that time, and require that nozzle can bear the high temperature of 1400e to the modern steam turbine equipment nineties, if adopt metallic nozzle again, not only need to adopt refrigerating unit, and the life-span of nozzle is also very short.By 2000, its nozzle temperature will be increased to 2000e further, at this moment metallic substance is adopted can not again, can only adopt stupalith, pottery not only has good high-temperature mechanical property, and thermal stresses also can be avoided to corrode, simultaneously due to need not refrigerating unit be added, can reduce frictionloss and energy-conservation, therefore, it is a kind of desirable material.
201310278557.7 openly applied for a kind of new ceramics, without firing, firebrick powder, cement, coke powder, lime powder are become ceramic size by proportioning coagulation, but this stupalith all and in wear resistance is weak in processing performance, mechanical property, strength level, fracture toughness property level, and the present invention is with Al
