据“先进材料和工艺”杂志报道:美国佐治亚特兰大佐洽亚技术研究院正在用自蔓延铝热反应方法生产一种高质量的无污染的超细TiB_2粉末。这种超细粉末可用于半导体和飞行器的金属熔炼工艺中。该粉末已经成形制出熔炼铝的电极,并且用来代替普通的碳电极。佐治亚的工艺为:用TiO_2、B_2O_3及还原剂(铝或镁)填满容器。将一种熔丝插入混合物中,并加热到600～1000℃。热丝促进了氧化物和还原剂之间自蔓延反应的能量供应。这
According to “Advanced Materials and Processes” magazine reported: Georgia, Georgia, Georgia, Georgia Qiaya Technology Research Institute is using self-propagating aluminum heat reaction method to produce a high-quality non-polluting ultra-fine TiB_2 powder. This ultrafine powder can be used in metal smelting processes for semiconductors and aircraft. The powder has been shaped to produce aluminum-smelting electrodes and has been used in place of conventional carbon electrodes. Georgia’s process is: fill the container with TiO_2, B_2O_3 and reductant (aluminum or magnesium). A fuse is inserted into the mixture and heated to 600-1000 ° C. Hot filament promotes the energy supply of self-propagating reaction between oxide and reductant. This
