- silicon powder is added to the slurry to produce the first silicon carbide-based heat-resistant porous structure material
- the carbonized porous structure obtained thereby has a skeleton portion of carbon.
- an amorphous carbon portion formed by carbonization of the phenol resin and a silicon powder are mixed on the surface portion, and the carbon powder skeleton is covered.
- the shape of the tangible skeleton is almost the same as the original shape without being deformed or shrunk.
- the carbonized porous structure has a processable strength.
- the carbonized porous structure becomes 130 to 140 in a vacuum or an inert atmosphere after the carbonization.
- the amorphous carbon from the phenolic resin reacts with the silicon to form porous silicon carbide on the tangible skeleton. This results in the formation of porous silicon carbide due to wettability with molten silicon.
- this reaction is a volume reduction reaction, so that open pores are generated on the surface due to the volume reduction reaction. As a result, a porous structure having a surface portion formed of porous silicon carbide is obtained.
- the carbonized porous structure is placed under a vacuum or an inert atmosphere.
- the silicon carbide-based heat-resistant porous structural material of the present invention is obtained by melting and impregnating silicon at a temperature of 130 to 180 ° C.
- the second porous structural material corresponds to this case, and includes a molten silicon and a carbon powder having good wettability, and at the same time, a siliconized porous structure having carbon formed on the surface of the resin. Will be impregnated by melting.
- the mixing ratio of phenol resin and silicon powder is set to the ratio of carbon to silicon by carbonization of phenol resin to be 2: 3, and the phenol resin is dissolved with ethyl alcohol to prepare a slurry. Then, they were mixed in a ball mill for one day to reduce the particle size of silicon, impregnated in a laminated corrugated cardboard air conditioner filter made of activated carbon powder, and dried.
- this air conditioner filter was calcined at 1000 ° C. for 1 hour in an argon atmosphere to be carbonized.
- the obtained porous carbonaceous material had sufficient strength to be processed, and shrinkage was extremely small at about 3%.
- This carbonaceous porous body was subjected to reactive sintering and melt impregnation of silicon at 1450 ° C. for 1 hour under vacuum to obtain a corrugated cardboard-shaped heat-resistant porous silicon carbide composite material.
- the obtained heat-resistant porous silicon carbide-based structural material had the same structure as the corrugated cardboard as the raw material, the same dimensions as those after carbonization, and the surface was flat.
- the skeleton made of silicon carbide was different from that made of cardboard made of paper, and was thick and excellent in strength.
- a slurry was prepared by dissolving the phenol resin in ethyl alcohol, and impregnated in a laminated cardboard air conditioner filter made of activated carbon powder, followed by drying. Next, this air conditioner filter was calcined at 1000 ° C. for 1 hour in an argon atmosphere to be carbonized. The obtained carbonaceous porous material has sufficient strength for processing. And the shrinkage was extremely small at about 3%.
- This carbonaceous porous body was melt-impregnated with silicon at 144 ° C. for one hour under vacuum to obtain a corrugated cardboard silicon carbide heat-resistant porous composite material.
- the obtained silicon carbide heat-resistant porous structural material had the same structure as the corrugated cardboard as the raw material, the same dimensions as those after carbonization, and the surface was flat.
- the skeleton made of silicon carbide was different from that made of cardboard made of paper, and was thick and excellent in strength.
- An air-conditioning filter in the form of a laminated corrugated cardboard made of activated carbon powder was calcined at 1000 ° C. for 1 hour in an argon atmosphere to be carbonized.
- the obtained porous carbon material became powdery when touched, and did not retain its shape.
