Rheological and technological properties of chromic oxide slips and castings

Conclusions An investigation of the rheological properties of chromic oxide slips showed that their optimum casting interval lies in an acid medium at pH not above 3. In this case the zeta potential is at maximum, the viscosity at minimum, and the building-up rate and density of the casting high.Firing in a mild reducing medium gave chromic oxide specimens of porosity 14–16% and a cold-crushing strength of 1300–1700 kg/cm².Translated from Ogneupory, No. 2, pp. 42–46, February, 1976.
