nonstoichiometric

After the precursor's thermal decomposition under the protection of nitrogen,a kind of nonstoichiometric titanium oxide can be prepared.

用钛粉和草酸反应制得前驱物,保护下600℃热分解前驱物制备了一种非化学计量钛氧化物。

In the presence of impurities or in a nonstoichiometric solid, free electrons or electron holes are produced as a result of “charge compensation” to neutralize the effect of charged ionic defects 。

杂质存情况下，或非化学计量比固体中，为了中和带离子缺陷所引起不平衡，便会产生自由子或子空穴。
