metals have been used for decades in a wide variety of industrial
applications because of their outstanding mechanical and catalytic
properties and their resistance to corrosion, oxidation and
temparature. One of this application is in gauzes.
metal gauzes are needed principally for the catalytic combustion
of ammonia or are employed for the production of cyanic acid
(HCN) which is used as the raw material in the manufacture
of sodium cyanide (NaCN), potassium cyanide (KCN) and methacryclic
gauzes are produced by weaving thin wires, usually with a
diameter of either 0.076 mm or 0.060 mm. Typically, the gauzes
were woven with 1024 mesh/cm2.
Heraeus now produces precious metal catalyst gauzes with a
new structure : the warp knitting gauzes. Compared to the
conventional woven gauzes these offer a number of technological
and chemical advantages.
