Alternatively and more conveniently, K2O is synthesized by heating potassium nitrate with metallic potassium: Other possibility is to heat potassium peroxide at 500C which decomposes at that temperature giving pure potassium oxide and oxygen. ), IMDG: 8 (For reference only, please check. It is near about 740 C and it starts decomposing at the temperature of 300C. The chemical formulas P 2 O 5 and K 2 O are the traditional means of expressing the percentage of phosphorus (P) and potassium (K) in fertilizer. Therefore, potassium oxide is alkaline in nature and is highly corrosive too. But these high rates of nutrient removal are not usually being matched with fertilization. We can use the simple rule, "Percent K and percent P equals 1.2 and 2.3," to convert from oxide to the elemental forms for phosphorus and potassium, that is, from . 2.
