仲钨酸铵对蓝钨性能影响较大，而蓝钨物理性能对钨粉和碳化钨粉的性能影响也较大，通过对APT煅烧前或煅烧后进行特殊处理优选蓝钨原料，可以制取优质碳化钨粉。

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。

As the results show, new type of polycarboxylic acid-based admixture and shrinkage reducer reduce the negative influences of volume shrinkage.
