Preparation method:
Burn high-purity metallic indium in the air or calcine indium carbonate to generate In2O, InO, In2O3. Finely control the reduction conditions to obtain high-purity In2O3. Spray combustion process can also be used to obtain indium trioxide ceramic powder with an average particle size of 20nm.
When indium hydroxide is burned to prepare indium trioxide, if the temperature is too high, In2O3 may be thermally decomposed. If the temperature is too low, it is difficult to completely dehydrate, and the generated oxide is hygroscopic. Therefore, heating temperature and time are important factors. In addition, because In2O3 is easily reduced, it must always be kept in an oxidizing atmosphere.
Burn indium hydroxide in the air at 850℃ to constant weight to generate In2O3, and then heat it in the air at 1000℃ for 30min. Other indium nitrates, indium carbonates, and indium sulfates can also be burned in the air to obtain indium trioxide.
Applications:
✔ Used as spectrally pure reagents and materials for electronic components, etc.
✔Used as protective coatings for metal reflective mirrors, optoelectronic display semiconductor films
✔ Manufacture of transparent electrodes and transparent heat reflector materials for the production of flat-panel liquid crystal displays and defoggers
Properties and stability:
In the presence of hydrogen or other reducing agents, it can be reduced to metallic indium or low-valent indium oxides when heated to 400-500°C.
It decomposes into low-grade oxides at high temperatures. In addition, it can react with metallic indium at high temperatures. Although In2O3 generated by low-temperature calcination is easily soluble in acid, the more completely it is treated at high temperatures, the less soluble it becomes, and its hygroscopicity disappears. When indium trioxide is reduced with hydrogen in a red-hot state, metallic indium is generated.
