Production process:

1. High temperature solid-state reaction method: Mix metal lanthanum with graphite powder in proportion, with graphite usually in excess of 5% to 10%. The mixture is placed in a Pyrex reaction tube and gradually heated to 1700 ℃ by induction heating under inert atmosphere (such as argon or helium) protection, and kept at that temperature for about 30 minutes. Then, it is naturally cooled to obtain lanthanum carbide product. This method needs to be operated in a glove box to ensure complete isolation from air and moisture.
2. Arc melting method: Weigh high-purity lanthanum metal and carbon powder in a stoichiometric ratio, mix and press them into blocks in a vacuum glove box (pressure of about 25-40 tf/in). The pressed block is then placed in an arc melting furnace and subjected to arc melting in a high-purity helium or argon atmosphere, allowing the metal to fully react with carbon to produce lanthanum carbide. This method is suitable for preparing high-purity and dense lanthanum carbide materials.
3. Hydrogen intermediate gas method: First, react metal lanthanum with hydrogen gas to generate lanthanum hydride (LaH3), and then mix lanthanum hydride with graphite powder uniformly under argon protection. The mixture is heated to 1200 ℃ in a vacuum furnace and kept at that temperature for 30 minutes, allowing lanthanum hydride to react with carbon to form lanthanum carbide (La ₂ C3). This method is commonly used to prepare lanthanum carbide tungsten composite hot cathode materials, which can reduce reaction temperature and improve product uniformity.
