Specialty Metal Oxides
Backed by many years of experience in solid state oxide chemistries, the development of new tin oxide chemistries is still a key activity of ours here at Keeling & Walker.
Modification of chemical and physical properties to match specific application-related requirements has led to a range of very unique products.
Fluorine Tin Oxide (FTO)
FTO is an off-white powder with good electrical conductivity. It easily forms opaque dispersions, which are used for conductive coatings on glass as semi-transparent heating areas or for electrodes in solar cells.
Precious Metal Doped Tin Oxides
Modern gas sensor materials rely on doped tin oxides as detector materials, which show excellent responses to several gases. Doped tin oxides with tailored precious metal loadings are available.
Keeling & Walker offers tailored tin oxides with specific particle size distributions for the deposition of sensor materials via inkjet printing or coating processes.
High Purity Indium Oxide
Despite the fact that Indium Oxide is a rare Oxide, it finds many uses in High Tech Industries. Indium Oxide is a key component of sputtering targets for thin film applications. Its property as reflector for Near Infrared Light is exploited in optical coatings and specialty mirrors. Furtheron Indium Oxide finds use in Electrical Contact Materials and Sensor Materials.
Keeling&Walker manufactures a high purity (> 99.99%) grade. The Oxide consists of agglomerated nanoscale particles with an average primary particle size of 20 – 40 nm.
