Indium Oxide In2O3 Powder CAS 1312-43-2

About Indium Oxide In2O3 Powder:
Indium oxide is an amphoteric oxide of indium, and the molecular formula is 2O3. The pure product is a white or light yellow amorphous powder, which is heated to reddish-brown. Indium oxide is a new n-type transparent semiconductor functional material having width disabled bandwidth, smaller resistivity and higher catalytic activity, and has been widely used in optical fields, gas sensors, and catalysts. In addition to the above functions, there is also an indium oxide particle size, surface effect, quantum dimensional effect, small dimensional effect, macroscopic quantum tunnel effect.
Indium oxide is presented in hydrogen or another reducing agent, heated to 400 to 500 ° C, reduced metal indium or low-cost oxide. The low-level oxide is separated at high temperatures. Further, at a high temperature, it can react with metal indium solubilized in acid, but the more difficult it is, and the moisture absorption also disappears. When hydrogen is reduced by heating through hydrogen, metal indium is produced.
Indium oxide is insoluble in water but can be dissolved in acid, while crystalline oxides are not soluble in water. The crystals are divided into two phases, cubic (diamond type) and diamond (corundum). The bandgap between the two phases is 3eV. The parameter of the cubic phase is listed in the information box. A rhombic phase is produced at high temperatures and is produced using a non-balanced growth method.

How is Indium Oxide In2O3 Powder produced?
1. The high-purity metal indium is burned in the air or indium carbonate is calcined to produce In2O, Ino and In2O3, and the high-purity In2O3 can be obtained by finely controlling the reduction conditions. The indium trioxide ceramic powder with an average particle size of 20nm can also be prepared by the spray combustion process.
2. When indium hydroxide is burned to prepare indium trioxide, if the temperature is too high, In2O3 has the possibility of thermal decomposition; if the temperature is too low, it is difficult to complete dehydration, and the oxide generated has hygroscopic property. Therefore, heating temperature and time are important factors. In addition, because In2O3 is easily reduced, it must always be kept in an oxidizing atmosphere.
3. Indium hydroxide is burned in the air at 850℃ to a constant weight to generate In2O3, and then heated in the air at 1000℃ for 30min. Other indium nitrates, indium carbonate, and indium sulfate can also be burned in the air to make indium trioxide.

What exactly is Gadolinium oxide? Gd2O3 is the chemical formula for gadolinium dioxide. It has a molecularweight of 362.498000 with a melting temperature of 2330 and a density 7.407. It is white in color.

Physical And Chemical Properties of Gadolinium Oxide

Gadolinium oxide is a white, odorless and amorphous powder. It is not soluble, however it can be broken down by acid to create the salt. Exposure to air makes it easy to absorb carbon dioxide from the air and cause it to deteriorate. It reacts with ammonia and can precipitate gadolinium-hydrate.

Preparement Method of Gadolinium Oxide

To make micron-grade gadolinium dioxide powder, mix 10g with hydrochloric acids at 3.23mol*L. Then heat the mixture until it is completely reacted. Finally, add some polyethylene glycol to the solution (which disperses the gadolinium salt). After the colloidal precursor has been stable for quite some time, stir the mix to disperse and dissolve polyethylene glycol. Deionized water was mixed with the prepared colloid. This gave rise to 500 mL suspension. It was then dried by spray drying. For nano-gadolinium, oxide is obtained by calcining the precursor at different temperatures (600-900) over several hours.

How To Easily Prepare Dysprosium Oxide Luminescent Materials

What’s Dysprosium Oxide? Dysprosium Oxide is a chemical substance that has the chemical formula Dy2O3. The white powder is slightly hydrophobic and can absorb water as well as carbon dioxide from the air. Magnesium is stronger than that of high iron oxide. Insoluble in acid and alcohol. Primarily used in lighting.

Dysprosium oxide

1. Chemical and physical data

The relative molecular masses of dysprosium dioxide are 373.00 and (d274) 8.81 respectively. The melting point for the material is approximately 234010°C. The boiling point is around 3900°C.

2. Property of physical and chemical substances Dysprosiumoxide is a white crystal powder. It’s insoluble when water is used, but can be dissolved in acid or ethanol. Exposure to the air causes it to absorb carbon dioxide, which turns into dysprosium-carbonate.

Dysprosium oxide

is the Main Use Dysprosium dioxide can be used to make dysprosium and as an ingredient for glass and neodymium-iron boron magnets. As an additive to permanent magnets made of neodymium metal boron, dysprosium can be also used. The coercivity of a magnet may be increased by adding about 2 to 3.3% dysprosium. There was a small demand in the past for dysprosium. But with NdFeB, this element is now a necessity. The grade should be between 9599.9%. And the demand is growing rapidly. Also, dysprosium oxide can be used to make dysprosium metallic, an additive for glass and neodymium-iron boron permanent magnetics.

Prepare Dysprosium Oxide-Luminescent Material

You will need to weigh the correct amount of Europium Oxide and Dyprosium Oxide powder. After preparing ionic Solution A, heat and stir. Finally, you can add to solution B by heating and stirring. The solution is ready to be used once it’s evaporated at 80°C. You quickly transfer the solution to the corundum container and seal it. The high-temperature resistance furnace can be preheated up to 600°C. Next, place the container containing the precursor solution in the furnace and quickly close the door. Once heated, the precursor solution instantly boils and produces large amounts of heat. It takes approximately 5 minutes to complete the entire process. Once the sample has been removed, it can be cooled at room temp. It is a porous, loosely porous product that has a yellowish-green color. You can grind the product into SrAl2O4;Eu2+ and Dy3+ luminescent materials powder. The initial illuminance is 15lux, with an additional 12h afterglow. The emission peak is at 510nm. When the luminescent particles reach a nanometer size, then the relative Eu and Dy contents change or the crystall lattice is damaged. The luminous brightness of light is decreased or no light is emitted. But if the particle size is too large, it will make the coating film unevenly or not smooth. This test shows that the luminescent dust has a particle size greater than 75mm.
