Tantalum-containing pitch as a carbon precursor was synthesized by an in situ liquid phase reaction between coal tar pitch and tantalum pentachloride.

以煤沥青为原料，氯化钽为钽源，通过化学反应制备了含钽沥青前驱体。

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。

Jorge Posada hit a leadoff single, reaching third when centerfielder Torii Hunter let it get past him, and scored on Silva's wild pitch. Matsui doubled and scored on a single by Abreu, who was safe when shortstop Jason Bartlett failed to hold the throw on an attempted steal. One out later, Cano was hit by a pitch by Juan Rincon. After the runners moved up on Damon's comebacker, Cabrera singled to drive in both. He took second on the throw to the plate and scored the fifth run of the inning on the second of Jeter's three hits.

Jorge Posada率先击出安打，并且因为中外野手Torii Hunter 让球滚到身后而登上三垒，再趁Silva的暴投得分，松井击出二垒安打后靠著Abreu的一垒安打得分，Abreu则因游击手Jason Bartlett无法接住传来的球而盗上二垒，在一人出局之后，Cano被Juan Rincon的触身球打上一垒，两位跑者靠著Damon打回给投手的滚地球推进之后，Cabrera击出一垒安打把他们都送了回来，并趁球传回本垒时上到二垒，最后靠Jeter三支安打中的第二支得到该局的第五分。
