摘要：

A mixture of rutile, boron oxide and magnesium has been ball milled together with the intention of inducing a reaction to form titanium diboride, The resultant powders were examined by differential thermal analysis, isothermal annealing and X-ray diffraction to determine the effect of milling on the formation of TiB2. Complete reaction was found to occur in the mill between 10 and 15 h forming TiB2 and MgO with no residual Mg. The unwanted phase, MgO, was readily removed by leaching in acid leaving a fine powder composed of aggregates of TiB2. The feasibility of using this relatively simple, low technology route to value add for minerals is also discussed. (C) 1999 Published by Elsevier Science Ltd. All rights reserved.
