The samples with smaller grain sides were obtained in our experiment, and the properties are corresponding with that of those samples prepared by melting method mentioned previously. several approaches can be proposed for further increasing the thermoelectric properties. preparation of the material with different compositional deviations availably controlled from stoichiometry is one of the ways to change the carrier concentration, and hence to optimize the value of power factor
該方法獲取的塊體樣品的片狀顆粒的粒度遠小於熔煉法制備的樣品，樣品的性能也與熔煉法相當，如果能有效控制樣品的化學計量比，提高生成物的純度將會更大程度的提高材料的熱電性能。 -
From the particle settling point of view, the main factors affecting the compositional distributions of sediment have been analyzed. the result indicates that there exists quantitative relation between the compositional distributions of sediment and the settling quality ratio of the powders a and b. only the ratio varies does the compositional distributions of sediment change
結果表明：當有兩種不同種類的粉未a 、 b共同沉降時，沉積體的組成分佈與單位時間內a 、 b粉末的沉降量比存在定量關系，只有單位時間內a 、 b粉末的沉降量比變化時，沉積體的組成分佈才發生變化。
