Abstract

Potassium halogenthiophosphates K6PS5Br and K6PS5Cl as well as halogen-free K7PS6 compound were synthesized using the two-step technique from elemental substances as well as potassium halides. The elemental composition of the obtained samples was determined using energy-dispersive X-ray spectroscopy. Raman spectra of K6PS5Br and K6PS5Cl show themselves to be much similar to those of chemically related Cu6PS5Br and Cu6PS5Cl argyrodite crystals. The much richer spectra of K6PS5Br and K6PS5Cl as well as K7PS6, however, reveal that their structure most likely differs from the cubic structure of Cu6PS5Br and Cu6PS5Cl argyrodites. doi: https://doi.org/10.15407/spqeo22.01.26 PACS 78.40.Ha; 77.80.Bh
新型含钾银矾型化合物的合成与表征
以单质和卤化钾为原料,采用两步法合成了卤代硫代磷酸钾K6PS5Br和K6PS5Cl以及无卤K7PS6化合物。使用能量色散X射线光谱测定所获得的样品的元素组成。K6PS5Br和K6PS5Cl的拉曼光谱显示它们自己与化学相关的Cu6PS5Br和Cu6PS5Cl银石晶体的拉曼光谱非常相似。然而,K6PS5Br和K6PS5Cl以及K7PS6的更丰富的光谱表明,它们的结构很可能与Cu6PS5Br和Cu6PS5Cl的立方结构不同。doi:https://doi.org/10.15407/spqeo22.01.26PACS 78.40.Ha;77.80亿
