Synthesis of Nanocrystalline (Ti,W)(B,C,N) Powders AITranslate
Abstract AITranslate
Nanocrystalline （Ti,W）（B,C,N） powders were prepared by precursor plus carbothermal reduction with metatitanic acid,ammonium metatungstate,xylose and boracic acid as the materials. Phase composition and microstructure of the products were characterized by SEM and XRD. The effects of synthesis temperature and holding time on reaction products were discussed. The results show that both synthesis temperature and holding time have obvious effects on the synthesis of （Ti,W）（B,C,N） powders. With the increase of synthesis temperature and holding time, synthetic powder grains significantly grow up. Nano- crystalline （Ti,W）（B,C,N） powders with grain size of 21.3 nm are successfully prepared at 1 200 ℃ for 2 h. Compared with the traditional method of ordinary ball milling plus carbothermal reduction, the method of precursor plus carbothermal reduction can significantly reduce synthesis temperature with an advantage of low cost of raw materials.
