Note that all perchlorates are vigorous oxidizing agents and the risk of explosion is high especially if materials are dried.  Exercise the utmost caution with these materials.

Dear alan sir,

Thanks for your valuable answer. But I have noticed some remarkable observations by the addition of perchloric acid to leady oxide. leady oxide is a mixture of lead oxide and metallic lead . I have taken 50 g of this leady oxide, to this I have added 5-10 g of 70% perchloric acid slowly by drop by drop at room temperature and stirred for 15 min . kept the whole reaction mixture in hot air oven and dried for 20 hrs. at 60C. To know the phase composition of the reaction mixer, samples are analyzed in XRD.  

I have observed the following phase composition:

Before perchloric acid addition to the leady oxide, I have subjected the samples to XRD analysis to know the phase composition of leady oxide. Presence of PbO (80%) and Pb (20%) was observed.

where as the leady oxide is mixed with perchloric acid, observed the presence of PbO2 (Lead dioxide), Pb3O4 (Red lead), lead oxide (PbO) and Pb.

Is there any scope to form such compounds when PCA is added to leady oxide.

Be careful . The product will be lead perchlorate and is shock sensitive. Initially the lead oxide dissolves and then the mossy lead metal slowly dissolve.
