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

|
|
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 quality tin oxides to meet the demanding requirements
of the ceramic industry. |
|
The
Thermox Range of tin oxide materials
|
|
A range of tin oxide materials offering
grades which span a wide range of particle size and specific
surface area, suitable for many applications including high
quality ceramic pigments, automotive friction and brake materials
and tin oxide electrodes for glass melting. |
|
|
|
The
CS Range of tin oxide electrical contact materials
|
|
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 |
Metastannic
Acid
|
|
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
|
|
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. |
|
| Nano-particulate
materials |
Tin
Oxide Nano-Particulate Powders
|
|
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-Particulate Dispersions
|
|
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
|
|
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 (99.999%) tin oxide
|
|
Our high purity tin oxide grade
is carefully produced from 99.999% purity tin metal in order
to provide a tin oxide with 99.999% purity. This
material is used for sputtering targets and any application,
which requires an ultra-high purity tin oxide. We also produce high purity meta and aphla stannic acids. |

|
Keeling & Walker Limited are
experts 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. |
