中文摘要 | 不同Cr₂O₃/CrPO₄比例的磷酸鉻系材料以共沉澱法製備,其熱學性質以X光繞射、熱重分析和微分熱分析鑑定。結果顯示磷酸鉻以Cr₂O₃和CrPO₄成份存在,二者並未形成單一化合物,但會互相阻礙晶體成長,使其熱學性質較安定。 |
英文摘要 | A series of chrominophosphates, CrPs, with various Cr₂O₃/CrPO₄ ratios were prepared by coprecipitation. Thermal properties of the CrPs were characterized by X-ray diffraction, by thermogravimetric analysis, and by differential thermal analysis. The results reveal that the nonstoichiometric CrPs form a nearly physical admixture of Cr₂O₃ and CrPO₄ as two individual compounds that mutually inhibited crystallization, resulting in a high thermal stability. |
