In a broad sense, it refers to all fibers made from ceramics, excluding glass fibers. Examples include silica fiber, alumina fiber, mullite fiber, zirconia fiber, and silicon carbide fiber. In a narrow sense, it refers to fibers with an alumina-silica ratio of 1. There are long fibers and short fibers of about 250 mm, and due to their heat resistance and light weight, they are widely used in insulation materials, aerospace components, etc., and research into their use as construction materials is also underway. Of the short whiskers, silicon carbide has attracted attention, and composite materials as engineering ceramics are being developed.

広義にはセラミックスで製造された繊維で,ガラス繊維を除くすべての繊維を指す。シリカ繊維,アルミナ繊維,ムライト繊維,ジルコニア繊維,炭化ケイ素繊維など。狭義にはアルミナ-シリカ比が1の繊維を指す。長繊維と 250mm程度の短繊維があり,耐熱性,軽量性という特徴から断熱材料,宇宙航空機部材などに広く用いられ,建設材料としての研究も進められている。長さの短いひげ結晶 (ウィスカー) では炭化ケイ素が注目され,エンジニアリングセラミックスとしての複合材料開発が行なわれている。
