Potassium permanganate can be used to prepare transition metal oxide catalysts, often by adding other metal oxides to enhance the activity of such catalysts. Activity of such catalysts by adding other metal oxides. A mixture of one part granulated sugar and two parts potassium permanganate, ground in the middle of a dry piece of wood, will burn quickly and effectively if the weather is dry. When there is no fire-starting material in the field and you need to start a fire, you can use the antifreeze and potassium permanganate left inside the used car to mix and grind, then wrap the newspaper and knead it into a ball, and it will burn in less than 10 seconds.
