Abstract

The vapor composition of the TaC–ZrC mixed carbide system was examined in the vicinity of its melting domain. Single-phase TaC–ZrC carbide samples of different compositions (with a mole fraction of TaC from 50 to 95 %) were prepared and their laser-induced vaporization was analyzed using time-of-flight mass spectrometry. The measurements of relative partial pressures of the main vapor species of TaC–ZrC carbide were taken in the temperature range from 4200 to 4550 K. It was established that in vapor, the atomic ratios of Zr/Ta and C/(Zr+Ta) depended only on the composition of the carbide itself, but were independent of temperature. Moreover measured C/(Zr+Ta) atomic ratio was close to 1.3 in a wide composition range except the situation when the fraction of TaC in the carbide is more than 95 %.

4550k激光蒸发TaC-ZrC混合碳化物的质谱研究

在熔点附近对TaC-ZrC混合碳化物体系的气相组成进行了研究。制备了不同成分（TaC摩尔分数为50% ~ 95%）的单相TaC - zrc碳化物样品，并利用飞行时间质谱分析了其激光诱导汽化。在4200 ~ 4550 K的温度范围内测量了TaC-ZrC碳化物的主要汽相的相对分压。在水蒸气中，Zr/Ta和C/(Zr+Ta)的原子比只与碳化物本身的组成有关，而与温度无关。除碳化物中TaC含量大于95%外，在较宽的组成范围内，测得的C/(Zr+Ta)原子比均接近1.3。

期刊介绍： The Journal of the American Ceramic Society contains records of original research that provide insight into or describe the science of ceramic and glass materials and composites based on ceramics and glasses. These papers include reports on discovery, characterization, and analysis of new inorganic, non-metallic materials; synthesis methods; phase relationships; processing approaches; microstructure-property relationships; and functionalities. Of great interest are works that support understanding founded on fundamental principles using experimental, theoretical, or computational methods or combinations of those approaches. All the published papers must be of enduring value and relevant to the science of ceramics and glasses or composites based on those materials. Papers on fundamental ceramic and glass science are welcome including those in the following areas: Enabling materials for grand challenges[...] Materials design, selection, synthesis and processing methods[...] Characterization of compositions, structures, defects, and properties along with new methods [...] Mechanisms, Theory, Modeling, and Simulation[...] JACerS accepts submissions of full-length Articles reporting original research, in-depth Feature Articles, Reviews of the state-of-the-art with compelling analysis, and Rapid Communications which are short papers with sufficient novelty or impact to justify swift publication.
