The results showed that three reasons caused the failure of the fibre materials:1the fibre materials transforming into powder which was caused by the precipitation of mullite at high temperatures;2cracking and spalling of the refractory coating and refractory fibre felt;3low strength of the refractory fibre flet.

结果表明：硅酸铝质耐火纤维在高温下析出莫来石晶体导致纤维材料的粉化，耐火涂层和耐火纤维毡的开裂、剥离脱落，耐火纤维毡强度很低是导致纤维材料失效的3个主要机理。研究结果为新型耐火材料的研制或改进提供了重要依据。

Their matrix in glass phase, apparently exists newborn mullite phase, it is precisely because of their formation, the crisscross raphides increased structure strength.

Using high alumina mullite as rawmaterial, cement or micro-powder as binding agents, the Hi-Al2O3 castables is one unshaped refractory and has the benefits of high strength,especially under medium temperature, and good thermal shock resistance.

高铝浇注料是以高铝莫来石原料为主，以水泥或微粉为结合剂的不定型产品，具有强度高，特别是中温强度高，热震性好的特点。

Figure 5 and 6 of the comparison, we can find that, in the 3 - B sample for fine powder, including new mullite quantity than A - 11 samples.

由图5和图6的比较可以发现：B-3试样中因细粉量增大，其中新生莫来石量大于A-11试样。

The proper alkaline content was in favor of compressive strength. The chemically combined water of paste without activator decreases with the increase of fly ash content, the content of Ca2 decreases after 28d. The increase extent of chemically combined water of pastes with NaOH is higher than that of without activator, and the paste with Ca2 is the same. The XRD peak of Ca2 of paste without activator is high at early age, and the peak of mullite and quartz has less change along with age. When NaOH is added, the peak of quartz of fly ash has clear drop. The surfaces of fly ash activated has eroded trace at 7 d.

研究结果表明：适量碱的掺入对强度有利；未掺激发剂浆体的化学结合水量随着粉煤灰掺量的增加而减少，Ca2含量在28d后开始下降；掺NaOH浆体的结合水量随龄期增长的幅度比未掺激发剂的浆体的大，而掺Ca：试样变化较小；未掺激发剂的水泥－粉煤灰体系在早期Ca2的峰值较大，且粉煤灰中的莫来石和石英晶体的衍射峰随龄期变化不大；NaOH掺入后，28d时，粉煤灰中的石英晶体衍射峰明显下降；时于掺激发别的试样，在7d时粉煤灰颗粒表面已被腐蚀。
