Keeling & Walker Limited supplies many products for use in different areas of application, from ceramic colours to electrical contact materials, glass-melting electrodes and catalysis.

Tin oxide for ceramic pigments and glazes

data link

  Tin oxide is a versatile material for ceramics. Its thermal stability and chemically inert nature enables the production of a wide palette of durable ceramic colours.

In ceramic applications the physical characteristics and chemical purity of the tin oxide are of major importance. We have developed a comprehensive range of high performance tin oxides to meet the demanding requirements of the ceramic industry.
Tin oxides from Thermox Performance Materials Ltd

data link 		  This range of high performance tin oxide materials offers products which span a wide range of particle size and surface area, suitable for many applications including high quality ceramic pigments, automotive friction materials, grades for glass refining and bubble reduction, and materials suitable for the manufacture of tin oxide glass melting electrodes.
Electrically conductive and infrared reflective / absorptive materials
The CP Range – Antimony tin oxide

data link 		 

The StanoStat CP Range offers white or light-coloured electrically conductive ATO materials, which are an alternative to metal powders or carbon black to give antistatic properties to plastics, paints and coatings. They provide the opportunity to produce light or coloured antistatic and infrared absorptive coatings and plastic parts.
The CPM Range – Antimony tin oxide nanoparticles

data link 		  The StanoStat CPM range of ATO products exhibit nano-particulate primary particle size and can be used for transparent electrically conductive coatings on a variety of substrates including glass and plastic. Additionally, these materials are ideally suited for the production of sputtering targets.

Keeling & Walker supplies these materials in powder form or as nano-particulate dispersions in a variety of solvents. These dispersions are ready for use in transparent electrically conductive and infrared reflective coatings, and can be formulated into inks for inkjet and other printing techniques.
Indium tin oxide nanoparticles

 data link 		  Our indium tin oxide material is comprised of nano-sized particles, providing good electrical conductivity and infrared performance. The material is suitable for the manufacture of sputtering targets or as a basis for the development of printing inks.
Fluorine tin oxide

 data link 		  Our fluorine tin oxide material is comprised of sub-micron fluorine-doped tin oxide, which is white in colour and provides good electrical conductivity.
The CS Range of tin oxide electrical contact materials

data link 		  A carefully controlled range of tin oxide grades for use in silver / tin oxide electrical contact materials, produced to exacting standards to provide the optimum particle size for the utmost performance and durability in this demanding application.
Hydrated tin oxide materials
Metastannic Acid

 data link 		  Metastannic acid is a hydrated tin oxide, which exhibits an extremely high specific surface area and nano-particulate primary particle size. This material finds application as a specialised grade for the production of ceramic pigments and for catalysis.
Alphastannic Acid

data link 		  Alphastannic acid is another hydrated tin oxide, with a more granular structure than the metastannic acid grade. It has been developed for use in catalysis but also finds use as an ion-exchange medium in the separation of radionuclides.
Other nano-particulate materials
Tin Oxide Nano-Particulate Powders

 data link 		  Keeling and Walker can supply tin oxide with ultra-fine particle size in the nanometre range. Nano-particulate materials provide enhanced functionality, which makes them particularly suitable for an increasing number of novel applications, including specialised ceramic pigments and catalysis.
Tin oxide nano-particle dispersions

data link 		  A number of aqueous based colloidal dispersions have been developed which contain nanometre size hydrated tin oxide or antimony doped tin oxide particles. These products have been developed for use in applications where ultra-fine tin oxide is required, for example to prepare transparent conductive coatings, for use in catalysis and as a source of highly reactive tin oxide with high surface area.
High surface area tin oxide

data link 		  Tin oxide doped with small additions of certain elements provides a range of tin oxide based materials with high specific surface area and small particle size. These products exhibit excellent temperature stability and find application in catalysis or gas sensor technology.
High purity tin oxide (99.99%)

data link 		  Our high purity tin oxide grade is carefully produced from 99.999% purity tin metal in order to provide a tin oxide of better than 99.99% purity. This material is used for sputtering targets, and any application which requires an ultra-high purity tin oxide.
Other materials

contact link 		  Keeling & Walker Limited is expert in producing solutions to specific customer requirements. If we do not have a suitable grade for the customer application we will endeavour to develop a bespoke material tailored to the customer’s specification.
