Palladium (II) Nitrate Solution
Palladium (II) nitrate is manufactured and supplied by EZOCM JSC as a solution, which is a dark brown heavy liquid.
Chemical formula for palladium (II) nitrate: Pd(NO3)2.
Palladium nitrate is used in the production of vehicle exhaust gas catalytic converters, for producing of various catalysts, and for the synthesis of palladium-based chemical compounds.
Palladium nitrate solution is produced in a variety of types that differ by the content of rationed impurity elements. The list of rationed impurity elements in palladium nitrates can be changed upon agreement between the customer and the manufacturer
