Foam silicon carbide ceramic and preparation method thereof |
| abstract |
The invention relates to a friction material preparation technology, in particular to a foam silicon carbide ceramic and a preparation method thereof. The preparation method of the foam silicon carbide ceramic is characterized in that silicon carbide is used as a raw material and is prepared through a foaming-pouring-sintering process; the sintering takes alumina, yttria and amorphous SiBCN as sintering aids. The preparation method provided by the invention can prepare the foam silicon carbide ceramic material with the average pore diameter of about 1mm and higher strength at a lower temperature. |
