Abstract
The invention discloses a method for preparing carborundum ceramic, which comprises the following steps: mixing bamboo charcoal with silicon powder after crushing and grinding bamboo charcoal by solid phase sintering, according to the mass ratio of 1 to 3, and evenly mixing the mixture of silicon and charcoal with phenolic resin according to the weight volume ratio of 1 to 1; preheating the mixture at the temperature of 140 DEG C for molding; under the state of vacuum or Ar gas atmosphere, increasing the temperature to the set final sintering temperature for high-temperature sintering; maintaining the temperature for 30 minutes, and cooling the mixture to produce the SiC ceramic material. In the method, carbide materials can be produced by an organic texture of bamboo materials through high-temperature sintering, the bamboo materials are charred under anaerobic condition to produce a charcoal frame with a bamboo pore structure, and the charcoal frame can be used as a biological template for ceramic phase filtering and reacting. The ceramic obtained through filtering and sintering reactions of metal or inorganic non-metal substances not only has a fine structure of bamboo, but also increases the reacting area, improves the resultant velocity, and has advantages superior to the prior ceramic preparation method.
Description
Technical field
The present invention relates to a kind of preparation method of silicon carbide ceramics.
Background technology
The research for preparing the SiC pottery by biomaterial at present focuses mostly on aspect the timber, almost do not utilize bamboo charcoal to prepare the research of this high performance stupalith aspect, therefore the 26S Proteasome Structure and Function to bamboo charcoal carries out theoretical research under present case, and further expanding bamboo charcoal, to utilize approach and exploitation be that the product innovation of raw material has important theory and realistic meaning with the bamboo charcoal.
Summary of the invention
At the problem that prior art exists, the object of the present invention is to provide a kind of preparation method of silicon carbide ceramics, present method utilizes the bamboo biological structure by the available carbide ceramics material of high temperature sintering.
For achieving the above object, the preparation method of a kind of silicon carbide ceramics of the present invention is specially:
1) adopts solid state sintering, behind the bamboo charcoal powder breakdown mill, mix by mass ratio 1:3, then the silicon-carbon mixture of unit weight (g) and the resol of unit volume (ml) are mixed by 1:1 with silica flour;
2) mixture in step 1 preheats moulding under 140 ℃, and block test specimen is prepared in cooling;
3) under vacuum (vacuum tightness 28Pa) or Ar gas atmosphere state (gaseous tension of Ar gas is 0.012MPa), the final sintering temperature that temperature is elevated to setting is carried out high temperature sintering;
4) keep temperature 30min, naturally cool to room temperature afterwards, make the SiC stupalith.
Further, described final sintering temperature is 1500 ℃, 1650 ℃ or 1800 ℃.
Further, during described high temperature sintering, before 200 ℃, carry out sintering, after 200 ℃, reach final sintering temperature with the heat-up rate of 15 ℃/min with the heat-up rate of 5 ℃/min.
The preparation method of a kind of silicon carbide ceramics of the present invention, the carbide material that utilizes the bamboo biological structure to obtain by high temperature sintering, bamboo wood carries out the charcoal skeleton that charing obtains having the bamboo wood pore texture under anoxic condition, and be processed into Powdered, with this biological template that infiltrates and react as ceramic phase, by metal or inorganic non-metallic material infiltrate, sintering reaction, make the pottery that obtains not only have the fine structure of bamboo wood, and increased reaction area, improve resultant velocity, had the incomparable advantage of general ceramic preparation.

Embodiment
Bamboo charcoal base carbide ceramics is exactly the carbide material that simulation utilizes the bamboo biological structure to obtain by high temperature sintering.Bamboo wood carries out the charcoal skeleton that charing obtains having the bamboo wood pore texture under anoxic condition, and be processed into Powdered, infiltrate as ceramic phase and the biological template of reaction with this, by metal or inorganic non-metallic material infiltrate, sintering reaction, make the pottery that obtains have the fine structure of bamboo wood.Reaction formula according to Si+C → SiC, the preparation method of a kind of silicon carbide ceramics of the present invention, be specially: at first adopt solid state sintering, behind the bamboo charcoal powder breakdown mill, mix by mass ratio 1:3 with silica flour, then the silicon-carbon mixture of unit weight (g) and the resol of unit volume (ml) are mixed by 1:1; The mixture of above-mentioned silicon-carbon mixture and resol is preheated moulding under 140 ℃, block test specimen is prepared in cooling; Under vacuum (vacuum tightness 28Pa) or Ar gas atmosphere state (gaseous tension of Ar gas is 0.012MPa), the final sintering temperature that temperature is elevated to setting is carried out high temperature sintering with block test specimen; Keep temperature 30min, naturally cool to room temperature afterwards, make the SiC stupalith.In order to study the characteristic of the SiC stupalith that makes under the differing temps, be 1500 ℃, 1650 ℃ or 1800 ℃ with final sintering temperature in the present embodiment, SiC stupalith such as Fig. 1, Fig. 2 and shown in Figure 3 of under these three kinds of temperature, making.And, for in sintering process, raw material interacts fully, make that final SiC stupalith is superior in quality, when high temperature sintering, before 200 ℃, carry out sintering with 5 ℃ heat-up rates, discharging the remaining oxygen in the sintering container, after 200 ℃, reach final sintering temperature with the heat-up rate of 15 ℃/min.
Test-results finds that along with the rising of temperature, through the SiC stupalith of high temperature sintering, color shoals gradually, and hardness diminishes gradually, its for the bamboo carbon component in the silicon-carbon compound due to hot conditions reacts completely; The meticulous vesicular structure of bamboo wood is simulated and utilized to present method, and making has increased reaction area when producing the SiC stupalith, improved resultant velocity, makes the preparation process of SiC stupalith simplify greatly.The present invention has given the new intension of bamboo wood and these two kinds of traditional materials of pottery, helps realizing the high value added utilization of bamboo wood, promotes the Sustainable development of bamboo charcoal industry and ceramic industry.
