    • Description:
      "A Bureau of Mines turbomill was evaluated for use in the production of high-purity, ultrafine alpha-silicon carbide powders suitable for advanced ceramics that could substitute for high-temperature alloys containing critical materials such as chromium, cobalt, and nickel. The effect of milling parameters, such as type of dispersant, temperature, pH, and gas environment, on the milling of alpha silicon carbide was studied. The addition of dispersants improved the grindability of alpha silicon carbide. Of the six dispersants studied, the best results were obtained with Marasperse N-22. Grinding efficiency was also increased when the alpha silicon carbide was milled in a basic slurry and at an elevated temperature. Gas environments did not appear to affect grinding of alpha silicon carbide. Optimum grinding efficiency was obtained at 50 C in a slurry at pH 9.5 with Marasperse N-22 as the dispersant. Under these conditions, minus 100- plus 200-mesh alpha silicon carbide was ground to 80 pct less than 1 micrometer in 4h." - NIOSHTIC-2 NIOSHTIC no. 10005765
