Simple method of preparing pure platinum dioxide
- 15 Downloads
PtO2 molecules are readily formed in the collision of rapidly moving platinum atoms with free oxygen molecules, and, by condensing on the walls of the glass vessel, which is at room temperature, they readily form the known hexagonal lattice of this compound.
At an oxygen pressure of about 10−1 mm in a flask having a volume of about 200 cc, the deposit obtained contains an insignificant amount of unchanged metal.
