【摘要】 本文报道了对新型锑酸镉半导瓷Cd₆Sb₂O₁₀进行差热分析、热失重分析和高温X射线衍射分析的实验结果,并进行了系统地分析和讨论。结果表明,Cd₆Sb₂O₁₀在240℃左右发生一结构相变,高温相具有较高的对称性,此相变是可逆的,从低温相向高温相转变时,相变温度为246℃,从高温相向低温相转变时,相变温度为228℃。更多还原

【Abstract】 The thermal analysis and X-ray diffraction analysis on Cdr,Sb2O10 semiconductivc ceramics are carried out systematically, and the results are discussed. It is indicated that a structural phase occurs in Cd6Sb2O10 at about 240℃　and the high temperature phase possesses a higher symmetry.The phase transition is reversible and transition temperature are 246℃ and 228℃ respectively.更多还原
