In March 2004 JSC Krastsvetmet
launched a new kind of product – knitted platinum alloy
catalyst gauzes for nitric acid industry. The technology
was taken up from the English company Johnson Mattey
Plc., the world market leader.
Today we produce three types of knitted gauze:
- NitroLok;
- ProLok;
- HiLok,
specially designed for maximum efficiency of ammonia oxidation process and prussic acid production.
Gauze wire size varies from 60 to 92 microns.
Six types of alloys are used for wire production:
- Pt/Rh - 95/5
- Pt/Rh - 92/8
- Pt/Rh - 90/10
- Pt/Rh/Pd - 90/5/5
- Pt/Rh/Pd - 81/16/3
- Pt/Rh/Pd/Ru - 81/15/3,5/0,5
The alloys composition, wire diameter and knitting type are chosen
to meet optimally the customer’s requirements. A catalyst pack
installed can be constructed of gauzes knitted of wire of various
sizes and alloys. A pack can be made of gauzes of several different
knitting types.
