在发现具有Mo5O14结构的三元Ge W氧化物之后，对大量的三元M W O系统进行了调查，以调查这种结构类型的出现频率。通过将氧化钨和适当的三元元素或三元元素的适当化合物在抽空的二氧化硅安瓿中在1373°K下加热1周来制备样品。所研究的组成接近于M0.02W0.98O2.80。Mo5O14结构的氧化物存在于整个周期表的许多系统中，从Li到Bi。讨论了这些相形成的一些方面以及它们影响WO3还原为W金属过程的方式。
Following the discovery of a ternary GeW oxide with the Mo5O14structure, a large number of ternaryMWO systems were surveyed to investigate the frequency of occurrence of this structure type. Samples were prepared by heating tungsten oxides and the appropriate ternary element or a suitable compound of the ternary element in evacuated silica ampoules at 1373°K for 1 week. The compositions investigated were close toM0.02W0.98O2.80. Oxides with the Mo5O14structure were found in many systems across the whole of the periodic table, from Li to Bi. Some aspects of the formation of these phases and the way in which they could affect the course of reduction of WO3to W metal are discussed.
