ALUMINA FIBERS, ALUMINA FIBER AGGREGATE, AND RETAINING MATERIAL FOR USE IN EXHAUST GAS PURIFICATION DEVICE
To provide alumina fibers that can form an alumina fiber aggregate that, when made into a retaining material for an exhaust gas purification device, has sufficient holding power of a catalyst support and can reduce variation in bearing stress.SOLUTION: The present invention provides alumina fibers in which the content of sodium oxide is 530-3200 ppm, and the mass ratio (A/B) of the content of the sodium oxide (A) and the content of calcium oxide (B) is 5 to 116.SELECTED DRAWING: None
【課題】排ガス浄化装置の把持材とした際に、触媒担体に対する十分な保持力を有し、かつ、面圧のばらつきを低減できるアルミナ繊維集合体とすることができるアルミナ繊維を提供する。【解決手段】酸化ナトリウムの含有量が５３０〜３２００ｐｐｍであり、前記酸化ナトリウムの含有量（Ａ）と酸化カルシウムの含有量（Ｂ）との質量比（Ａ／Ｂ）が５〜１１６であるアルミナ繊維である。【選択図】なし
