Abstract

The present work describes the synthesis of WC nano particles directly from wolframite ore which is the main source of tungsten (W). The systematic experimental conditions describe that high purity WC nano particles of nearly 12 nm can be synthesized using solvo-thermal route and selecting appropriate experimental condition (particle size, carbon source and heating temperature).
