Theoretical analysis and experimental results indicate that reaction of zinc with selenide as fully as possible under H2-O2 flame at about 1500℃ is the key step in the synthesis process and prolonging holding time at high temperature, which makes the diffuse reaction adequately take place, is favourable to obtain stoichiometry ZnSe polycrystalline.

理论分析和实验研究均表明：前期H2-O2焰下高温灼烧(~1500℃)使Zn和Se充分反应，是合成工艺的关键；延长后期恒温时间（不少于2周），使扩散反应进行完全，有利于获得更接近化学计量比的ZnSe多晶料。
