摘要：

An easy processing route has been developed for a nano-sized crystalline tungsten mono-carbide (WC) material. Starting materials for WC synthesis were made by simply mixing tungstic acid (H2WO4) and polyacrylonitrile (PAN) powders. The starting powders were applied to heat treatment at 1200 degrees C for 30 min with an argon gas flow in an alumina tube. Tungsten mono-carbide has been successfully synthesized in PAN/H2WO4 weight ratios of more than 0.6. The acquired WC powder had a nano-sized crystalline and high-specific surface area. Crystalline size and specific surface area were estimated to approximate 50 nm and 17.2 m(2) g(-1) respectively. (C) 2012 The Ceramic Society of Japan. All rights reserved.
