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] and rhombohedral (corundum type). Both phases have a band gap of about 3 eV. [3] [4] The parameters of the cubic phase are listed in ...
Although most compounds are referred to by their IUPAC systematic names ... Indium(I) oxide – In 2 O; Indium(III) oxide – In 2 O 3; Iodine pentoxide – I 2 O 5;
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]
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 ...
Indium(I) compounds are not common. The chloride, bromide, and iodide are deeply colored, unlike the parent trihalides from which they are prepared. The fluoride is known only as an unstable gas. [42] Indium(I) oxide black powder is produced when indium(III) oxide decomposes upon heating to 700 °C. [38]
Indium compounds are chemical compounds that contain the chemical element indium ... Indium tin oxide; Indium trihydride; Indium(I) iodide; Indium(II) chloride;
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.
Numerous investigations have found an explanation for this effect. The oxygens of the carbonyl and the hydroxyl group chelate the indium of the organoindium intermediate as illustrated below on the left by the two green bonds. The incipient C-C bond, illustrated in red, creates a six-member ring in a chair conformation.
