Sažetak
Very high temperatures are needed to prepare W-B compounds. However, the results obtained in this study demonstrate a possibility of inducing the formation of W2B, WB or WB4 tungsten borides, in air and at room temperature, using the high-energy ball-mill treatment on appropriate compositions of the W-B elemental powder mixtures. The present results throw a new light on the synthesis of tungsten borides, and on the accuracy of the equilibrium W-B phase diagram.
