What is chemical vapor transport? Chemical vapor transport means that in a sealed quartz tube, at a certain temperature, the reactant reacts or acts with a certain transport factor (such as HgCl, HgBr, HgI and PtCl), and then, transported to another temperature to undergo a recrystallization process in the form of a gas phase, so that the product crystal grains are sufficiently grown to obtain a desired product. Some experts have prepared MxWO3 (M=K, Rb, Cs) by chemical vapor transport method. The process is like a sublimation or distillation process, but at such a temperature, MxWO3 (M = K, Rb, Cs) does not pass through a vapor phase it should have, so it is called chemical vapor transport.
