Abstract
A production method of an artificial mineral, the method crystallizing an amorphous precursor gel containing one or more kinds of metal elements by a synthesis reaction in which the amorphous precursor gel is heated and pressurized under a predetermined condition, the method including freezing and drying the amorphous precursor gel before the synthesis reaction. Freezing the amorphous precursor gel fixes the aggregated state of elementary units in the amorphous precursor gel, so that when the amorphous precursor gel is dried and crystallized, an artificial mineral having a predetermined crystal structure can be obtained.
Claims14
A production method of an artificial mineral, the method crystallizing an amorphous precursor gel containing one or more kinds of metal elements by a synthesis reaction in which the amorphous precursor gel is heated and pressurized under a predetermined condition, the method comprising:
- freezing and drying the amorphous precursor gel under a predetermined condition before the synthesis reaction,
- wherein
- the amorphous precursor gel contains one or more kinds of elements selected from scandium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, gallium, yttrium, zirconium, niobium, molybdenum, ruthenium, rhodium, palladium, silver, cadmium, indium, tin, lanthanoid elements, hafnium, tantalum, tungsten, rhenium, and osmium, and
- in the amorphous precursor gel, an element contained in the amorphous precursor gel has a coordination structure having a hexacoordinated octahedron as a unit structure, and at least some unit structures are heterogeneous hexacoordinated octahedrons in which two ligands among six ligands are different from other four ligands.
