The reason that it is called potassium oxide is that potassium oxide is a binary ionic compound, thus it follows the rules for binary ionic compounds.
12.
It is formed as potassium reacts with oxygen in the air, along with potassium oxide ( K 2 O ) and potassium superoxide ( KO 2 ).
13.
In ceramics, the alkalis in feldspar ( calcium oxide, potassium oxide, and sodium oxide ) act as a flux, lowering the melting temperature of a mixture.
14.
One alternative material is "'crystal glass "', in which barium oxide, zinc oxide, or potassium oxide are employed instead of lead oxide.
15.
Potash imports and exports are often reported in " K 2 O equivalent ", although fertilizer never contains potassium oxide, per se, because potassium oxide is caustic and hygroscopic.

Potash imports and exports are often reported in " K 2 O equivalent ", although fertilizer never contains potassium oxide, per se, because potassium oxide is caustic and hygroscopic.
17.
Three species are formed during the reaction : potassium oxide, potassium peroxide, and potassium superoxide formed of three different oxygen-based ions : oxide ( ), peroxide ( ), and superoxide ( ).
18.
The catalyst the industry use is a promoted iron catalyst, where the promoters can be K 2 O ( potassium oxide ), Al 2 O 3 ( aluminium oxide ) and CaO ( calcium oxide ) and the basic catalytic material is Fe.
19.
K 6 Mn 2 O 6 is prepared as ruby-red crystals by the reaction of excess potassium oxide with manganese ( II ) oxide in a sealed nickel bomb at 610 �C for ten days . The Mn 2 O anion has an Al 2 Cl 6-type structure.
20.
Both phosphorus and potassium fertilizers are needed to maximize the leguminous cover plants'symbiotic nitrogen-fixation potential of approximately 200 kg nitrogen / ha / yr, and are applied to most soils at 115 to 300 kg phosphorus oxide / ha and 35 to 60 kg potassium oxide / ha.
