Platinum Q Salt® Product name Platinum electroplating solution This system is used to produce bright and highly adherent deposits of low stress and low porosity platinum. It has the added advantage of being non-toxic and non-explosive. Chemical formula [Pt(NH3)4](HPO4) Availability Platinum Q Salt® plating solution Pt 5Q (Product code - 155050) Product code* UK - 155067 UK - 155050 CN - 1046009 Platinum Q Salt® replenisher (pH 10 adjusted) Pt 20Q (Product code - 155067) * This product can be ordered worldwide under the UK and CN product codes. CAS Number 127733-98-6 Product family Pgm compound solution (aqueous) Process Electroplating Market Aerospace www.chemicals.matthey.com Johnson Matthey, Orchard Road Royston, SG8 5HE, UK Tel. +44 1763 253000 © Johnson Matthey 2015 Bath preparation The bath is supplied as a solution containing 5 g/l of platinum. This solution will have a pH of 10.2 - 10.8 at 20°C. The bath should be heated to the operating temperature of 91°C - 93°C, and the pH adjusted to the working range of 10.0 - 10.6 (optimum 10.5). This adjustment can be made by the addition of sodium hydroxide solution (10 % w/v) to increase the pH. Regular addition of demineralised or distilled water is necessary in order to maintain the volume of the bath. Replenishment The platinum concentration of the bath should be maintained between 4 g/l and 6 g/l by adding Platinum Q Salt® Pt 20Q replenishing solution as required. Product code 155067, which is pH adjusted. Metal preparation Components should be degreased and cleaned by means of a procedure appropriate to the substrate in question. The bath has been used to plate copper, gold, nickel, titanium, stainless steel and super alloys.

This is because the cathode current efficiency is substantially reduced at temperatures below 89ºC. Regular checks are essential to ensure that the recommended pH range is maintained.
