Keeling & Walker Limited - From Stoke to the World,

As the world’s largest producer of tin oxide materials, Keeling & Walker Limited, based in Stoke-on-Trent in the heart of England, is a name to be reckoned with.

Founded in the early 1900’s, Keeling & Walker became a Limited Company in 1916, by which time it was a leading supplier of all types of ceramic materials, consumables, plant and equipment.

The Company realised the growing importance of tin oxide, which was used for ceramic pigments and as a glaze opacifier, and by 1932 had developed an improved method of tin oxide production, the origins of the present ‘Superlite’ process. By 1939 tin oxide was the main product.

 In 1964 a controlling interest in the Company was acquired by the Patino Group, represented then by Consolidated Tin Smelters, whose successor, Amalgamated Metal Corporation Plc, is still the parent company.

Since the 1980’s the Company has continued to develop innovative new tin oxide based materials to service an ever-growing range of applications across many industry sectors.

The Company was a pioneer in the development of ATO (antimony tin oxide) nanomaterials in the early 1980’s. The combination of optical transparency, electrical conductivity and infrared absorption that these materials offer has resulted in many applications for these versatile materials.

In 1998 the Company acquired the tin oxide manufacturing business of T.H. Goldschmidt AG. The addition of the ‘Thermox’ range of tin oxide materials considerably diversified the Company’s product portfolio and the business became the World Leader in the supply of tin oxide based materials.

Today the Company produces many grades of tin oxide, hydrated tin oxide, antimony tin oxide, and other speciality materials used in the ceramics, automotive and aerospace industries, glass manufacture, electrical contacts and infrared functional applications, to name but a few.

Keeling & Walker Ltd continues to specialise and excel in its core tin chemicals expertise, and to deliver innovative products supported by continuous investment in state-of-the art production facilities. Our team of technical experts is always eager to offer help and advice in the selection and use of our materials. We are also pleased to work with customers to develop bespoke materials for specific applications.
