Low‐Temperature Preparation of Titanium Carbide Coatings on Graphite Flakes from Molten Salts

Abstract

Titanium carbide (TiC)‐coated graphite for refractory castable applications was prepared via reacting titanium metal powder (∼45 μm) and natural graphite flakes (100–300 μm) for 5 h at 950°C in a KCl‐based salt in Ar atmosphere. TiC coatings formed on graphite flakes were uniform, crack‐free, and composed of nanosized particles (20–40 nm). The “template‐growth” mechanism played a dominant role in the coating formation process.
