摘要

In the present study, the production parameters of tungsten boride compounds by self-propagating high-temperature synthesis (SHS) method and following leaching process were investigated. In the SHS stage, the products consisting of tungsten borides, magnesium oxide, magnesium borate, and also minor compounds were obtained by using different initial molar ratios of WO_3, Mg and B_2O_3 as starting materials. In the leaching step, Mg containing byproducts, i.e. MgO and Mg_3B_2O_6, existed in the selected SHS product synthesized at 1:8:2.5 initial molar ratio of WO_3 :Mg:B_2O_3 were leached out by using aqueous HCI solution to obtain clean tungsten boride compounds at different experimental parameters which are time, acid concentration and temperature. The acid leaching experiments of the SHS product showed that optimum leaching conditions could be achieved by using 5.8 M HCI at 1/10 S/L ratio and the temperature of 80 °C for 60 min.
