بعض خواص ذوبانية زجاج البزموث المرئي الحاوي على 15% مول من أوكسيد الزنك مع حامض الفسفوريك المركز

الملخص EN

The conditions for reaction of visible bismuth glass containing 15% mole of ZnO with phosphoric acid at different tfmperatures were studied by the rotary disc method.

The reaction gave a white precipitate on the visible bismuth glass surface.

The white precipitate was isolated and characterized by (X-ray) analysis.

Some physico-chemical properties were studied such as the velocity of precipitate formation by the above method at the reaction area (0.04-0.49cm ) of different temperatures also the effective activiation energy was determined and it was found to be between 10 and 33kJ\mole.
