Platinum Black, Sintered Platinum, Iridium Black, Gold Black, Iridium Black

With over 30 years of experience in gas adsorption and catalysis Ceimig has unparalleled expertise in the development and manufacture of high quality HSA (High Surface Area) materials for the Gas Sensor industry.

Ceimig materials are comparable in price to other commercially available products but exhibit unparalleled quality, sensitivity and batch to batch consistency. Typically, Ceimig ‘Black’s’ outperform other commercially available sensor materials - in some instances customer have reported Ceimig Black’s to be up to 8 times more sensitive than other commercially available materials.

Ceimig’s attention to performance and quality results in reduced material usage, reduced waste, enhanced yield and improved process consistency for sensor manufacturers.
