美国3M陶瓷材料公司开发了一种陶瓷基复合材料。称为西可耐克司(Siconex)。是由主要成份为Al_2O_3、B和Si的特种陶瓷纤维和碳化硅基体组成,其中纤维占30％,SiC基体占70％。先把纤维按元件形状要求缠起来,再用化学气相沉积方法涂上SiC。这种复合材料的抗热冲击能力要比普通耐火材料高得多,而密度只是他们的10％。它可在1300℃连续使用,并且允许用到1500℃高温。用它做成的工业炉真空型喷咀镶块,用以代替普通耐火材料整体喷咀,使用寿命可以大大提高,而且由于轻、薄(只0.04～0.06吋)容易装卸搬运,所以问世以后,深受热处理、钢铁、有色金属和石油工业的欢迎。
3M ceramic materials company in the United States has developed a ceramic matrix composites. Known as Siconex. It is composed of special ceramic fiber and silicon carbide matrix with the main components of Al 2 O 3, B and Si, in which the fiber accounts for 30% and the SiC matrix accounts for 70%. The first fiber according to the shape of the element wrapped around, and then coated with chemical vapor deposition SiC. The thermal shock resistance of this composite material is much higher than ordinary refractory materials, and the density is only 10% of them. It can be used continuously at 1300 ℃, and allows the use of 1500 ℃ high temperature. The industrial furnace vacuum nozzle insert made of it can replace the ordinary refractory whole nozzle, the service life can be greatly improved, and because light and thin (only 0.04 ~ 0.06 inch) are easy to handle, Highly heat treated, welcomed by steel, nonferrous metal and oil industries.
