peroxyhydrates

Some compounds are hydrated by hydrogen peroxide, and i saw that many of them can be used as an oxidizer, for example, percarbonate, take sodium percarbonate for example, 2Na2CO3 · 3H2O2 is oxidizer, and an oxidizer can be hydrated by hydrogen peroxide too like Na2O2·2H2O2 wont the oxidizer become much more powerful if it is hydrated by hydrogen peroxide ?

has any one prepared sodium percarbonate here ?

Sodium percarbonate is produced industrially by reaction of sodium carbonate and hydrogen peroxide, followed by crystallization. Also, dry sodium carbonate may be treated directly with concentrated hydrogen peroxide solution. World production capacity of this compound was estimated at several hundred thousand tonnes for 2004.[3] It can be obtained in the laboratory by treating the two substances in aqueous solution with proper control of the pH[4] or concentrations.

this seems like a very easy oxidizer to make, does any one know if i make copper percarbonate with with copper carbonate ?

For a propellant oxidizer , perhaps a peroxide salt. Commercially available
peroxidate addition compounds are quite ineffective don't waste your effort.

The only real use for Percarbonate is as a bleaching detergent.

Yes, well because percarbonate is a very bad.. oxidizer... i believe oxidizer-peroxyhydrates might be useful, like Na2O2(H2O2)2

I strongly believe that Na2O2 + H2O2 would make oxygen and NaOH instead...
