Abstract （Ti，W）（C，N，B） powders were prepared from precursors by the carbothermal reduction method. Meanwhile， the effects of different carbon and nitrogen sources on phase composition and morphology of reaction products were investigated by XRD and SEM. The results show that nanocrystalline （Ti， W）（C， N， B） solid solution powders with single-phase structure are prepared at 1 200 ℃ when xylose and nitrogenare are used as carbon and nitrogen sources， respectively， and the operation process is simple and easy to control. When carbon black and phenolic resin with high molecular weight are used as carbon source， urea is used as nitrogen source， the carbothermal reduction and solid solution process are easily hindered， which result in a large number of intermediate phases of titanium oxide （such as Ti3O5， Ti2O3， etc.） and impurity phase （such as W） in reaction products.

Key words： Key words: precursor carbothermal reduction (Ti, W)(C, N, B) solid solution powder carbon sources nitrogen sources
