Johnson Matthey produces a range of specially designed platinum alloys for use within the glass manufacturing industry.

The production and shaping of glass produces the harshest environment for the durability of materials as molten glass is exceptionally corrosive. Platinum alloys are used because they provide excellent resistance to corrosion, temperature stability, strength and non-reactivity. These properties are critical in the melting, mixing, transfer and forming of glass. Greater longevity of production components reduces plant downtime, improves the quality of products and has associated environmental and financial benefits.

Novel techniques have been developed to spray platinum alloys onto ceramic or metal substrates. This process is called ACTTM, Advanced Coatings Technology. This high technology solution means that products are made accurately whilst minimising the use of precious metal. This makes products more affordable and minimises the need for extraction of primary metal, and the related environmental impacts.
