Catalyst carriers: re-evaluation is a painstaking job, but we recommend it to you in the case of these SiC carriers. For six important reasons: Our silicon carbide supports give you thermal conductivity that's higher than that of any other group of supports. They're physically tough—attrition loss of less than 5 % for all types after extended milling tests means less clogging and dusting losses for you. They're thermally tough—no worries about process heat, because SiC supports are stabilized by kiln firing and nothing under 1000°C will affect them. They're inert—the basic chemistry of our SiC supports helps insure the purity of your product. Silicon carbide is doing many jobs where other supports have failed—for one or more of the preceding reasons.
Our SiC carrier line is the most complete available— you can get porosities from about 20% up to 60% in the spheres, polysurfaces, or cylinders shown below. If you agree that it may be time to take another look at catalyst carriers, we'll be happy to send you a free test kit and brochure. The kit contains samples of 16 of our carriers—aluminum oxide, silica, and mullite, as well as silicon carbide. Please write to us on your letterhead. No obligation, but we do like to know where our kits go. Our address is Dept. AC-09, Refractories Division, The Carborundum Company, Latrobe, Pa.
