合成制备方法

以二氧化钛和炭黑为原料，将高纯二氧化钛和炭黑按比例充分混合，干粉混合物加压成形,用水平碳管炉或立式碳管炉，在氢气气氛下，于1900～2300℃还原制得块状TiC，经粉碎得碳化钛粉状产品。或者以海绵钛和炭黑为原料，将海绵钛（或钛合金、碳化物固溶物回收的钛屑）和炭黑按比例充分混合，在高纯氢气气流中加热至1500～1700℃反应制得碳化钛。

2.金属钛直接碳化

将钛粉末(由钠还原或由氢化钛分解而得，325目以下)和炭黑混合，并在大约0.98Pa的压力下成型。再将物料放入石墨容器，于高纯度氢的气流中加热至1500～1700℃使碳渗入。反应温度和保持的时间取决于原料种类、粒度以及反应性能等。

3.气相反应法

将四氯化钛的蒸气和含有烃(甲烷、苯等)的氢气混合后送到已由感应加热或由其他方法加热的用于沉积碳化钛用的基材上，使其反应析出碳化钛。反应条件如反应气的浓度比、反应温度、送气流速等不同，析出的碳化钛形态也不同。

用途

1.用作切削工具材料的添加剂和金属铋、锌、镉熔融坩埚，制备半导体耐磨薄膜，HDD大容量记忆装置。
