Abstract
Official abstract text for this publication.
A method for producing a halide includes heat-treating a mixed material in an inert gas atmosphere, the mixed material being a mixture of (NH 4 ) a MX 3+a and LiZ. The M includes at least one element selected from the group consisting of Y, a lanthanoid, and Sc. The X is at least one element selected from the group consisting of Cl, Br, I, and F. The Z is at least one element selected from the group consisting of Cl, Br, I, and F. Furthermore, 0<a≤3 is satisfied.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for producing a halide, the method comprising: heat-treating a mixed material in an inert gas atmosphere, the mixed material being a mixture of (NH 4 ) a MX 3 +a and LiZ, wherein the M includes at least one element selected from the group consisting of Y, a lanthanoid, and Sc, wherein the X is at least one element selected from the group consisting of Cl, Br, I, and F, wherein the Z is at least one element selected from the group consisting of Cl, Br, I, and F, wherein 0<a≤3 is satisfied, and wherein, in the heat-treating, the mixed material is heat-treated at a temperature of greater than or equal to 500° C. and less than or equal to 650° C. 2. The method for producing a halide according to claim 1 , wherein, in the heat-treating, the mixed material is heat-treated for a time period of greater than or equal to 1 hour and less than or equal to 72 hours. 3. The method for producing a halide according to claim 1 , wherein the M is at least one element selected from the group consisting of Y, Sm, and Gd. 4. The method for producing a halide according to claim 1 , wherein 0.5≤a≤3 is satisfied. 5. The method for producing a halide according to claim 4 , wherein a=3. 6. The method for producing a halide according to claim 1 , wherein the X is at least one element selected from the group consisting of Cl, Br, and I, and wherein the Z is at least one element selected from the group consisting of Cl, Br, and I. 7. The method for producing a halide according to claim 1 , the method further comprising: preparing the (NH 4 ) a MX 3 +a, wherein, in the preparing, the (NH 4 ) a MX 3+a is synthesized by a solid-phase reaction between M 2 O 3 and NH 4 X. 8. The method for producing a halide according to claim 7 , further comprising: after the (NH 4 ) a MX 3+a is synthesized, weighing the (NH 4 ) a MX 3+a and the LiZ according to a desired molar ratio; and pulverizing and mixing the (NH 4 ) a MX 3+a and the LiZ to form the mixed material. 9. The method for producing a halide according to claim 1 , further comprising: weighing the (NH 4 ) a MX 3+a and the LiZ according to a desired molar ratio; and pulverizing and mixing the (NH 4 ) a MX 3+a and the LiZ to form the mixed material. 10. The method for producing a halide according to claim 6 , wherein X is different from Z. 11. A method for producing a halide, the method comprising: heat-treating a mixed material in an inert gas atmosphere, the mixed material being a mixture of (NH 4 ) a MX 3+a and LiZ, wherein the X is at least one element selected from the group consisting of Cl, Br, I, and F, wherein the Z is at least one element selected from the group consisting of Cl, Br, I, and F, wherein 0<a≤3 is satisfied, and wherein M is Y. 12. The method for producing a halide according to claim 11 , wherein a=3. 13. The method for producing a halide according to claim 11 , further comprising: weighing the (NH 4 ) a MX 3+a and the LiZ according to a desired molar ratio; and pulverizing and mixing the (NH 4 ) a MX 3+a and the LiZ to form the mixed material. 14. The method for producing a halide according to claim 11 , wherein X is different from Z. 15. A method for producing a halide, the method comprising: heat-treating a mixed material in an inert gas atmosphere, the mixed material being a mixture of (NH 4 ) a MX 3+a and LiZ, wherein the M includes at least one element selected from the group consisting of Y, a lanthanoid, and Sc, wherein the X is at least one element selected from the group consisting of Cl, Br, I, and F, wherein the Z is at least one element selected from the group consisting of Cl, Br, I, and F, and wherein a=3. 16. The method for producing a halide according to claim 15 , further comprising: weighing the (NH 4 ) a MX 3+a and the LiZ according to a desired molar ratio; and pulverizing and mixing the (NH 4 ) a MX 3+a and the LiZ to form the mixed material. 17. The method for producing a halide according to claim 15 , wherein X is different from Z. 18. A method for producing a halide, the method comprising: heat-treating a mixed material in an inert gas atmosphere, the mixed material being a mixture of (NH 4 ) a MX 3+a and LiZ, wherein the M includes at least one element selected from the group consisting of Y, a lanthanoid, and Sc, wherein the X is at least one element selected from the group consisting of Cl, Br, I, and F, wherein the Z is at least one element selected from the group consisting of Cl, Br, I, and F, wherein 0<a≤3 is satisfied, and wherein, in the heat-treating, the mixed material is heat-treated at a temperature of greater than or equal to 500° C. 19. The method for producing a halide according to claim 18 , further comprising: weighing the (NH 4 ) a MX 3+a and the LiZ according to a desired molar ratio; and pulverizing and mixing the (NH 4 ) a MX 3+a and the LiZ to form the mixed material. 20. The method for producing a halide according to claim 18 , wherein X is different from Z.
