Abstract
Description
technical field
[0001] The invention relates to the development of two preparation methods and applications of a class of ankangite-type structural materials. It belongs to the field of preparation and application of inorganic materials. Background technique
[0002] Ankang Mine is a new natural mineral recognized by the International New Mineral Nomenclature Committee discovered by Comrade Xiong Ming in Ankang, Shaanxi in 1982. It is Ba, Ti (V, Cr) oxide, with a hollandite-type basic structure, and a general chemical formula: A x (B 8-y C y ) 8 o 16 , (0.5<x<1.6, 0<y<4) where A is a large cation, such as Ba, K, Rb, etc., B is a tetravalent small cation, such as Ti, Mn, etc., and C is a low-priced small cation such as: Al , Fe, Cr, V, Co, Ni, Zn, etc. In the structure, B-O octahedrons share edges to form double chains, and four groups of double chains share corners with each other to form a channel with a square column in the middle. The channel is filled ...
