Scandium metal or scandium oxide or a compound that decomposes into scandium oxide when heated; Aluminum metal or aluminum oxide or a compound that decomposes into aluminum oxide when heated; Zinc metal or zinc oxide or a compound that decomposes into zinc oxide when heated. are mixed in an atomic ratio of Sc, Al, and Zn in an atomic ratio of 1:1:3, and the mixture is heated at a temperature of 600°C or higher in the air, an oxidizing atmosphere, or Sc and
It can be produced by heating in a reducing atmosphere in which Al is not reduced to a trivalent ion state and Zn is not reduced to a divalent ion state. Commercially available starting materials used in the present invention may be used as they are, but in order for the chemical reaction to proceed quickly, it is better to have a small particle size, especially 10 μm.
It is preferable that it is below. Further, when used as an optical functional material or a semiconductor material, it is preferable to have high purity since contamination with impurities is avoided. Examples of compounds whose starting materials yield metal oxides by heating include hydroxides, carbonates, and nitrates of the respective metals. The raw materials are thoroughly mixed as they are or together with alcohols, acetone, etc. The mixing ratio of the raw materials requires that the atomic ratio of Sc, Al, and Zn be 1:1:3. If this is removed, a single phase of the target compound cannot be obtained. This mixture is stored in the air, in an oxidizing atmosphere, or
At 600℃ in a reducing atmosphere where Sc and Al are not reduced from the trivalent ion state and Zn from the divalent ion state.
Heat under the above conditions. Heating time is several hours or more. There are no restrictions on the rate of temperature increase during heating. After heating, it can be rapidly cooled, or it can be rapidly drawn out into the atmosphere. The obtained powder of the ScAlZn 3 O 6 compound was colorless, and powder X-ray diffraction revealed that it had a crystalline structure. Its crystal structure is layered,
It was found that it was formed by stacking 1.5 layers of ScO, 2.5 layers of (Al, Zn)O, and a layer of ZnO. Example Scandium oxide (Sc 2 O 3 ) with a purity of 99.99% or more
Powder, aluminum oxide (Al 2 O 3 ) powder with a purity of 99.99% or higher, and reagent grade zinc oxide (ZnO) powder were weighed at a molar ratio of 1:1:6, and ethanol was added in an agate mortar. The mixture was mixed for about 30 minutes to obtain a fine powder mixture with an average particle size of several μm. The mixture was sealed in a platinum tube, placed in a tubular siliconite furnace set at 1450°C, and heated for 6 days, and then the sample was taken out of the furnace and rapidly cooled to room temperature. The obtained sample was a single phase of ScAlZn 3 O 6 , and the surface index (hkl),
The interplanar spacing (d p ) and relative reflection intensity (I%) were measured. The results were as shown in Table-2. The lattice constants as a hexagonal crystal system were a=3.242±0.001 (Å) and c=41.12±0.01 (Å). The above lattice constants and the surface index (hkl) in Table 2
