Catchment Gauze

The Plant manufactures gauzes of the following precious metals and their alloys: platinum Pt99.9, Pt99.8, platinum alloys PtRh93-7, PtRh90-10, palladium Pd99.9, Pd99.8, gold Au99.99, Au99.9, silver Ag99.99, and Ag99.9. The following alloys are used in catalyst and catchment gauzes production: PtPdRh92.5-4-3.5; PtPdRhRu81-15-3.5-0.5; PtRh92.5-7.5; PtRh95-5; PtRh92-8; PtRh90-10; PtPdRh90-5-5; PdW-5. Upon the Customer’s request the gauzes can be made of other alloys. Up-to-date computer control weaving machines produce gauzes of linen and twill weave.

For knitted gauze manufacturing the plant operates flat-knitting machines, including Stoll computerized machine which produces circular knitted gauzes from the very start of the knitting process. Afterwards the gauze is annealed in slot electric furnace or treated by hydrogen annealing to release work hardening and clean the surface.

Then the gauze is cut and subjected to electrochemical activation to guarantee high performance characteristics.

Micro gauze made of platinum (Pt99.9 and PtIr90-10) wire of 40 μm diameter for medical industry and instrument engineering can be considered a unique product of ours. Platinum micro gauze is subject to micro alloying for additional strengthening.
