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 ...
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]
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.
Tin(IV) oxide, also known as stannic oxide, is the inorganic compound with the formula SnO 2. The mineral form of SnO 2 is called cassiterite, and this is the main ore of tin. [9] With many other names, this oxide of tin is an important material in tin chemistry. It is a colourless, diamagnetic, amphoteric solid.
