Utwaramuriro

Utwaramuriro (kuturikira pyrophoricity muChingezi) zvinoreva chinhu chinoyerekana chapfuta moto choga mumhepo pasi pe54oC kana chinopfuta mukati memamineti mashanu (5mins) mushure mekunge chaiswa mumhepo. Mitombo ine utwaramuriro inosanganisira iron sulphide nesimbi dzinoti plutonium neUranium dzinopfuta dzega kana dziri paudha kana dzakavedzengwa kuita nhete.
