It was reported that lead dioxide could be prepared by the thermal oxidation of PbO or Pb3O4;however, White and Roy examined the products by X-ray diffraction and found that the oxide produced corresponded to an oxide with an active oxygen content of PbO

• 据报道,PbO2 可通过加热氧化PbO或Pb3O4来制备。white和Roy通过X-射线衍射对产品进行了检测,他们发现这一氧化产物相当于PbO。
