它们将长碳链通过N烷基化和酰化联接在一起的一类含硼表面活性剂，由于是含四配位硼氧杂环结构的表面活性剂和结合长碳链的基本性质从而极大的提高了表面活性。

Also, the effects of the amount of tantalum pentachloride and reaction time on the softening point of the pitch were investigated. Results showed that the tantalum particles were dispersed homogeneously in the pitch precursor with sizes in the range of 20-50nm. The tantalum particles mainly existed in the form of δ-Ta2O5 when the reaction temperature was 420℃. By further heat treatment,δ-Ta2O5 was transformed into β-Ta2O5 at 900℃.Β-Ta2O5 and TaC co-existed at 1200℃. At 2800℃, all the tantalum was transformed into TaC.

结果表明：沥青中钽化合物的粒度为20nm～50nm，主要以五氧化二钽的形式均匀分散于沥青中；惰性气氛下，较低温度(420℃)热处理时，钽化合物以δ-Ta2O5的形式存在，温度升高到900℃时，δ-Ta2O5转化为β-Ta2O5，在温度达到1200℃时，β-Ta2O5和碳化钽共同存在于炭基体中，在2800℃温度下，钽完全转化为碳化钽。

The properties of carbonized corn straw using as thermal insulating agent for liquid metal were investigated.
