Chemical compound
Indium(III) oxide (In 2 O 3 chemical compound , an amphoteric oxide of indium .
Physical properties [ edit ]
Crystal structure [ edit ]
Amorphous indium oxide is insoluble in water but soluble in acids, whereas crystalline indium oxide is insoluble in both water and acids. The crystalline form exists in two phases, the cubic (bixbyite type)[1] corundum type ). Both phases have a band gap of about 3 eV.[3] [4]
The rhombohedral phase is produced at high temperatures and pressures or when using non-equilibrium growth methods.[5] space group R 3 Pearson symbol hR30, a = 0.5487 nm, b = 0.5487 nm, c = 1.4510 nm, Z = 6 and calculated density 7.31 g/cm3 [6]
Conductivity and magnetism [ edit ]
Thin films of chromium -doped indium oxide (In 2−x Cr x O 3 magnetic semiconductor displaying high-temperature ferromagnetism , single-phase crystal structure, and semiconductor behavior with high concentration of charge carriers . It has possible applications in spintronics as a material for spin injectors.[7]
Thin polycrystalline films of indium oxide doped with Zn2+ are highly conductive (conductivity ~105 superconductive at liquid helium temperatures. The superconducting transition temperature T c [8]
Synthesis [ edit ]
Bulk samples can be prepared by heating indium(III) hydroxide or the nitrate, carbonate or sulfate.[9] sputtering of indium targets in an argon /oxygen atmosphere. They can be used as diffusion barriers ("barrier metals ") in semiconductors , e.g. to inhibit diffusion between aluminium and silicon .[10]
Monocrystalline nanowires can be synthesized from indium oxide by laser ablation, allowing precise diameter control down to 10 nm. Field effect transistors were fabricated from those.[11] redox protein sensors .[12] sol–gel method is another way to prepare nanowires.[citation needed
Indium oxide can serve as a semiconductor material , forming heterojunctions with p InP , n GaAs , n-Si indium trichloride solution, a method useful for manufacture of solar cells .[13]
Reactions [ edit ]
When heated to 700 °C, indium(III) oxide forms In2 I ) oxide or indium suboxide), at 2000 °C it decomposes.[9] [9] indium nitride is formed:[14]
In 2 O 3 3 2 O
With K 2 O 5 4 tetrahedral InO4 5− ions was prepared.[15] perovskites [16]
In 2 O 3 Cr 2 O 3 3
Applications [ edit ]
Indium oxide is used in some types of batteries, thin film infrared reflectors transparent for visible light (hot mirrors ), some optical coatings , and some antistatic coatings . In combination with tin dioxide , indium oxide forms indium tin oxide (also called tin doped indium oxide or ITO), a material used for transparent conductive coatings.
In semiconductors, indium oxide can be used as an n-type semiconductor used as a resistive element in integrated circuits .[17]
In histology , indium oxide is used as a part of some stain formulations.
