Title:
シチナカイト構造を有するシリコチタネートを含む組成物およびその製造方法
Document Type and Number:
Japanese Patent JP6645202
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a composition containing silico-titanate having a sitinakite structure capable of being manufactured without needs to use hazardous materials or deleterious materials, by using a compound easy to obtain and general purpose autoclave.SOLUTION: A silico-titanate composition is manufactured by being crystallized by using autoclave under a specific molar ratio. The composition contains niobium, has a sitinakite structure and diffraction peaks at least at 2θ=27.8±0.5° and 2θ=29.4±0.5° in an XRD pattern with CuKα ray (λ=1.5405Å) as a radiation source. The composition has higher strontium absorptivity than conventional strontium absorbents.SELECTED DRAWING: Figure 1
