    • This invention relates to a ceramic carbide fiber, a method for making the ceramic carbide fiber and an application of the ceramic carbide fiber. The ceramic carbide fiber comprises a carbide solid solution with at least two transition metals. The ceramic carbide fiber comprises a fiber diameter selected from a range of 10 μm to 200 μm. By the presence of two ore more different transition metals the stability of the ceramic carbide fiber is increased. The method for making the ceramic carbide fiber the method comprises providing a mixture with liquid precursors of the carbide solid solution in a solvent; converting the mixture into a gel precursor solution by at least partially cross-linking of the liquid precursors; drawing a green fiber of cross-linked precursors out of the gel precursor solution; drying the green fiber by removing solvent and pyrolysing the dried green fiber, whereas the ceramic fiber is formed. The sol-gel-technique is used to fabricate the green fiber resulting in a high homogeneity of the ceramic carbide fiber by thermal decomposition of the green fiber. Due to the high stability the ceramic carbide fiber is used as a filament component of a lamp.
    • 陶瓷碳化物纤维的制造方法,陶瓷碳化物纤维的制造方法以及陶瓷碳化物纤维的应用。 陶瓷碳化物纤维包括具有至少两种过渡金属的碳化物固溶体。 陶瓷碳化物纤维包含选自10μm至200μm范围内的纤维直径。 通过存在两种不同的过渡金属,增加了碳化硅纤维的稳定性。 制造碳化碳纤维的方法包括提供与溶剂中的碳化物固溶体的液体前体的混合物; 通过液体前体的至少部分交联将混合物转化成凝胶前体溶液; 从凝胶前体溶液中拉出交联前体的绿色纤维; 通过除去溶剂干燥绿色纤维并热解干燥的绿色纤维,而形成陶瓷纤维。 溶胶 - 凝胶技术用于制造绿色纤维,通过绿色纤维的热分解导致陶瓷碳化物纤维的高均匀性。 由于高稳定性,陶瓷碳化物纤维被用作灯的灯丝部件。
