本文详细介绍了溶胶-凝胶法制备非晶态药芯焊丝药芯的原理和工艺用Ti（OC4H9）4和Si（OC2H5）4为原料制备出了非晶态药芯，对非晶态药芯进行了X射线衍射分析、差热和热重分析结果表明：溶胶-凝胶法制备的非晶态药芯化学成分均匀、含氢量低、吸潮性小，能够满足焊接自动化生产对药芯焊丝药芯的要求，具有广阔的开发与应用前景
The principle and technology to produce amorphous flux for flux-cored wires by the sol--gel process were introduced in detail. Amorphous flux powders have been made from Ti(OC4H9)4 and Si(C2H5)4 and analysed with X--ray diffraction, TGA and DTA. The results show that the amorphous fuel powders produced by the sol-gel process have homogeneous chemical compositions, low residual hydrogen content and less moisture adsorption, which can meet the need of automatic welding production and has a good future for the development and applications.
