• Description:
  To identify construction materials for emerging technology in chemical and metallurgical processes, the Bureau of Mines investigated the acid resistance of ceramic materials. Eight commercial ceramic materials comprising two red shale, two fire clay, a silica, a five-clay-bonded silicon carbide, a carbon, and a high-alumina brick were evaluated. Samples were exposed for 110 days to 20 wt pct hcl at 50 deg, 70 deg, and 90 deg c and to 30 wt pct hcl at 70 deg c. Statistically significant changes in cold crushing strength, volume, and weight were generally small or not detected. The leach rates of al, ca, fe, k, mg, na, si, and ti ions were monitored. The carbon brick sample had the best acid-resistant properties with a maximum total leached ion weight loss of 0.004 Wt pct. The silicon carbide, the silica, and one of the fire clay bricks also had excellent acid-resistant properties. [Description provided by NIOSH]
