, the precipitate is not Sb4O5Cl2, but antimony trioxide (Sb2O3). The orthorhombic Sb2O3 content in the precipitate decreases and the cubic Sb2O3 content increases gradually with the increase...: antimony trichloride containing fluorine; neutralization-hydrolysis; antimony trioxide; cubic crystal; orthorhombic crystal 三氯化锑中和水解过程一般为三氯化锑首先水解为氯氧锑, 随着水解液中剩余酸度的降低, 其水解沉淀物相也发生了改变, 在通常情况下中和得到的为斜方晶型的氧......

WC/Mo2C比例对金属陶瓷组织和性能的影响张晓明1,2,傅又红1,2,彭凌洲1,2,温光华1,2,杨志峰1,21. 株洲钻石切削刀具股份有限公司2. 硬质合金国家重点实验室摘 要:研究了不同WC/(WC+Mo2C)值对TiCN-WC-Mo2C-Co-Ni金属陶瓷组织和性能的影响.通过分析SEM组织照片发现,随WC/(WC+Mo2C)值的增大,金属陶瓷的组织有黑芯硬质相减少,白芯硬质相增多的明显趋势.XRD图谱显示,添加Mo2C后组织中会出现一种与TiCN晶格常数差异稍大的(Ti,M)(C,N)物相,且其衍......
沥青碳纤维导电行为及其应用范晓波,姜荣跃,余宗森摘 要:对通用型沥青基预氧化纤维在碳化过程中的电阻变化行为进行了测试.结果表明:碳化过程中纤维的电阻率可由1012Ω-cm下降到10-1Ω-cm,得到了纤维电阻率与碳化温度之间的定量关系;并通过纤维电阻率的变化与纤维元素分析结果之间的对应关系,表明纤维在碳化过程中发生结构转变.给出了利用碳纤维导电性的应用实例.关键词:沥青基碳纤维;电阻率;碳化;......
