日本尼奇阿斯公司生产一种高铝纤维,商品名为鲁比松散纤维。这种高铝质纤維Al_2O_3含量高达95％,由于通过高温处理,以结晶化的α-Al_2O_3为主要成分,所以没有像以前的陶瓷纤维那样会由于析晶引起的纤维劣化或收缩,甚至到1700℃的高温还可以使用。其用途包括膨胀填充材料、隔热材料、
Nigerasi company in Japan produces a high-alumina fiber, the brand name of Ruby fibers. As high as 95% Al 2 O 3, the high-alumina fiber contains as its main component crystallized α-Al 2 O 3 by high-temperature treatment, there is no deterioration or shrinkage of the fiber due to crystallization as in the case of the conventional ceramic fiber, ℃ high temperature can also be used. Its uses include expanded packing, insulation,
