以ZrO2、Mg和炭黑为原料，在KCl溶液中合成了纯的亚微米级ZrC粉体。KCl对熔盐合成有较强的促进作用。结果，反应温度降低到800 ℃，这比迄今为止报道的大多数其他合成技术所使用的温度低得多。据信，在合成过程中，ZrO 2和炭黑都充当了“模板”。用本技术制备的高质量ZrC粉末可用于制备用于各种应用的重要ZrC基复合材料。
Pure submicron-sized ZrC powder was successfully synthesized in KCl by using ZrO2, Mg and carbon black as the starting raw materials. KCl showed strong accelerating effect on the molten salt synthesis. As a result, the reaction temperature was reduced to as low as 800oC, which is much lower than the temperatures used by most of the other synthesis techniques reported so far. It is believed that both ZrO2 and carbon black had acted as the “templates” in the synthesis process. High quality ZrC powders prepared with the present technique could be used for making important ZrC based composites for various applications.
