Ammonium Hexachloroplatinate IV CAS 16919-58-7 99.9pct Yellow Crystal Precipitating Agent for Potassium Platinum Recovery

1. Product Overview

Ammonium Hexachloroplatinate IV CAS 16919-58-7 is a high value platinum group metal compound also known as Ammonium Chloroplatinate. It presents as a distinctive light yellow to golden yellow crystalline powder. This material is slightly soluble in cold water and insoluble in ethanol and ether. It serves as a critical intermediate in platinum refining and is the classical gravimetric standard for potassium determination. Our product is manufactured under strict quality control to ensure high platinum content and low levels of base metal impurities.

2. Key Features & Advantages

• High Platinum Assay: Guaranteed platinum content of approximately 43.4 percent ensuring high yield in metal recovery processes.

• Excellent Crystallinity: Forms uniform cubic crystals which are easy to filter and wash in analytical procedures.

• Thermal Decomposition: Cleanly decomposes upon heating to yield high purity platinum sponge or platinum black without carbon residue.

• High Purity Options: Available in 99 percent 99.9 percent and 99.999 percent metals basis to meet diverse industrial and research needs.

• Reliable Precipitation: Exhibits sharp and quantitative precipitation with potassium ammonium rubidium and cesium ions in acidic media.

3. Main Applications

• Precious Metal Refining: Primary compound used in the purification of platinum from crude ore concentrates via precipitation and subsequent calcination.

• Analytical Chemistry: Used as a gravimetric reagent for the quantitative determination of potassium ammonium and other alkali metal ions in water and soil samples.

• Catalyst Manufacturing: Serves as a precursor for preparing platinum on carbon or platinum on alumina catalysts used in hydrogenation and petroleum reforming.

• Platinum Plating: Employed in the formulation of plating baths for depositing platinum coatings on electrical contacts and laboratory apparatus.

• Semiconductor Industry: Ultra high purity grades are used in Chemical Vapor Deposition CVD processes for depositing platinum electrodes in integrated circuits.
