Potassium oxide (K 2 O) is an ionic compound of potassium and oxygen. It is a base. This pale yellow solid is the simplest oxide of potassium. It is a highly reactive compound that is rarely encountered. Some industrial materials, such as fertilizers and cements, are assayed assuming the percent composition that would be equivalent to K 2 O.

2025年1月6日 · Potassium oxide is a strong alkaline flux which is similar to sodium oxide but is slightly less strong and it begins its fluxing action earlier than does sodium oxide, at approximately 1382°F (750°C). It's a predictable, stable flux that produces bright glossy glazes, but it can't be used alone as a flux.
