在鉴定云南某铂矿区重砂样品时,发现一种含钛较高的铬磁铁矿.据文献记载,铬尖品石类矿物中除Cr、Fe、Mg、Al主要元素外,还可含有微量的T i、V、Ni、M n和Ca等元素.它们多呈类质同象存在于铬尖晶石结晶格架中,而TiO_2则常形成钛铁矿,在铬尖晶石类矿物中呈固溶体.本文所研究的铁质铬磁铁矿,化学分析含T iO_23.95%,电子探针分析含TiO_24～5%,且Ti呈均匀状态分布.彭志忠教授认为,这是一种含钛较高的
In the identification of heavy platinum in a platinum ore area in Yunnan Province, a higher content of chromium magnetite was found.It is reported in the literature that the chromium tip-type stone minerals in addition to the main elements of Cr, Fe, Mg and Al may also contain Trace amounts of Ti, V, Ni, Mn and Ca etc. They are mostly isomorphic in the chromium spinel crystal lattice, and TiO 2 is often formed ilmenite, chromium spinel minerals In the solid solution.The iron chromium magnetite studied in this paper, chemical analysis with T iO 23.95%, electronic probe containing TiO 2 24 5%, and Ti was uniformly distributed state Professor Peng Zhizhong that this is a Titanium is higher
