Abstract: In the electrically heated quartz tube, most of GeH₄are directly atomized, i. e. , GeH₄(g) →Ge(s). Only a few of GeH₄are indirectly atomized, i. e. , GeH,i(g)→Ge(g)→Ge(s). When the temperature of the quartz tube is higher than₉₆₀K, oxygen in the gas entering the quartz tube will interfere with atomization of GeH₄, and the process of atomization is Ge(g) +(1/2)O₂(g)→GeO(g).
