Indium(III) oxide (In 2 O 3) is a chemical compound, an amphoteric oxide of indium. Physical properties ... Indium oxide can serve as a semiconductor material, ...
The oxides of indium in its preferred oxidation state of +3, namely In 2 O 3 and In(OH) 3 are weakly amphoteric; it forms anionic indates in strongly basic solutions. [112] Indium forms Zintl phases such as LiIn, Na 2 In and Rb 2 In 3. [113] Indium does not oxidize in air at ambient conditions. [109]
Many metals (such as zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. Aluminium oxide (Al 2 O 3) is an example of an amphoteric oxide. Amphoterism depends on the oxidation states of the oxide. Amphoteric oxides include lead(II) oxide and zinc oxide, among many others. [5]
Indium tin oxide and indium phosphide harm the pulmonary and immune systems, predominantly through ionic indium, [91] though hydrated indium oxide is more than forty times as toxic when injected, measured by the quantity of indium introduced. [21] People can be exposed to indium in the workplace by inhalation, ingestion, skin contact, and eye ...
Boron oxide (B 2 O 3) is slightly acidic, aluminium and gallium oxide (Al 2 O 3 and Ga 2 O 3 respectively) are amphoteric, indium(III) oxide (In 2 O 3) is nearly amphoteric, and thallium(III) oxide (Tl 2 O 3) is a Lewis base because it dissolves in acids to form salts. Each of these compounds are stable, but thallium oxide decomposes at ...
The precipitation of indium hydroxide was a step in the separation of indium from zincblende ore by Reich and Richter, the discoverers of indium. [ 6 ] Indium(III) hydroxide is amphoteric , like gallium(III) hydroxide ( Ga(OH) 3 ) and aluminium hydroxide ( Al(OH) 3 ), but is much less acidic than gallium hydroxide ( Ga(OH) 3 ), [ 5 ] having a ...
Indium tin oxide (ITO) is a ternary composition of indium, tin and oxygen in varying proportions. Depending on the oxygen content, it can be described as either a ceramic or an alloy . Indium tin oxide is typically encountered as an oxygen-saturated composition with a formulation of 74% In, 8% Sn, and 18% O by weight.
