SLIP-CASTING SLURRY FOR MANUFACTURING SILICON CARBIDE BODIES |
摘要 |
1. Slip casting composition for producing shaped bodies of silicon carbide with the use of silicon carbide, graphite, binders, floating agents and liquefying agents in a liquid medium, wherein the slip consists of silicon carbide powders of different grain fractions amounting to 48 to 65 mol- %, a graphite, resp. carbon portion amounting to 6 to 9.5 wt.- % and water in an amount of from 28 to 40 wt.- %, the liquefying agent being a melamin-formaldehyde-resin added in an amount of 0.15 to 0.35 wt.- % the binder being a polysaccharide added in an amount of 0.01 to 0.40 wt.- % together with 1.0 to 1.75 wt.- % of boric acid and the floating agent being ammonium alginate added in an amount of 0.10 to 0.25 wt.- % and the pH-value having been adjusted by the addition of 0.06 to 0.12 wt.- % of sodium hydroxide solution. |
