powder preparation by solid-state reaction
固相反应法制粉powder preparation饰solid-state reaction通过固相间反应制取固态化合物或固溶体陶瓷粉体的方法。由于在制取过程中反应物与生成物都处在固体状态下，故与气相或液相反应中的情况有较大的差异。在固体状态下，不同的原料以几微米或更粗的颗粒状态相互接触混合，此时原子、离子要通过缓慢的扩散、靠近才能起反应;同时由于生成物亦属于固体，如需要进一步反应，参加反应的原子、离子也必须扩散穿过生成物的体积内部。所以，在固相反应中，固体的集合状态不均匀，质点扩散距离远，反应迟钝，速度缓慢。 与固相反应发生的同时，常常伴随着出现固相烧结和重结晶。烧结是指固相反应中晶粒之间产生转移而粘接合并固结的现象;重结晶则是同种原料或生成物各自产生晶粒合并粗化的现象。同类粉料如果出现固相烧结，必然会降低原料粉粒的括性，从而增加质点扩散的难度，不利于固相反应的进行。 为了加快固相反应的速度，需使原料粉粒尽量细化(如磨细至l拜m或更小)，或适当加压以增加反应物接触的表面，或通过搅拌提高反应混合物的均匀性，以及合理地提高反应温度，使反应容易完成。 陶瓷工艺中用固相反应法制备粉体的流程见图。 首先将参加反应的各种原料按准确比例配料并置入}原料配制} 土{球磨棍合{卜}助磨剂{┌──────┐│反应锻烧 │├──┬─┬─┤│一自│轻│回││然 │压│转││堆 │成│搅││积 │型│拌│└──┴─┴─┘厂I颤口，巨遣亘巫二…一巨夔口，巨l更习固相反应法制粉工艺流程图球磨机中研磨混合。为了强化混合可加入助磨剂(通常是水、或者乙二醇及其他极性物质)。当原料充分混合磨细后，通过压滤、烘烤、喷雾或冷冻方法去除液体，最后进行锻烧完成反应。当反应物粉料以自然堆积方式进行反应时，效率较低，还可能使易挥发成分散失;如将粉料加压成型后再反应，则可加快反应，但相应地也有可能发生结块现象;如粉料采用管筒式回转窑转动搅拌缎烧，可使反应较迅速、完全、均匀，且可连续生产。由固相反应法生成的粉粒通常都有不同程度的烧结，或有粗化现象发生，通常还必须采用机械粉碎方法等，使之进一步细化。如发现有未反应原料剩余时，则必须进行再次反应锻烧再粉碎。反应良好的粉料，通常还要进行适当的造粒、存储，以备后续成型、烧结工艺使用。 (李标荣)
