摘要

报道包头矿的穆斯堡尔谱研究结果

其谱图系由两组四极双峰组成。A双峰是反映钛氧八面体中的Fe

而B双峰则反映钛氧八面体中的Fe

。Fe

/Fe

=1.32。结果表明:Fe

与Fe

同时存在于钛氧八面体晶位中

并与Ti呈类质同象。其中钛氧八面体的畸变特征类似于金红石的钛氧八面体。

Abstract

Baotite

first discovered in Baotou

Inner Mongolia

China and afterwards reported in Montana

U. S. A.

is a kind of tetracyclic Ba - Ti - Nb silicate and has low content of Fe （Fe2O3<3%）. The first report on its 57Fe Mossbauer spectrum is given in the paper . Two sets of quadrupole doublets are obtained from the spectrum. The A doublets is attributed to Fe3+ and the B doublet reflects Fe2+ in the Ti -O octahedra. Fe3+/Fe2+ = l. 32. The spectrum indicates that; （l）both Fe3+ and Fe2+ are present in baotite; （2）Fe3+ and Fe2+ exist as isomorphism in the octahedra; （3）the titanium octahedron is somewhat distorted

which is similar to the case of rutile; and （4）there may be a complicated structure in baotite crystal.
