Chemically bonded ceramic processing of mono-calcium aluminate
- Univ. of Illinois, Urbana, IL (United States)
A ceramic matrix composite consisting of mono-calcium aluminate as the matrix phase and calcia stabilized zirconia as the second phase was fabricated by warm-pressing. The hydraulic properties of calcium aluminate (CA) were exploited in order to form strong green bodies. Pressureless sintering of composites with zirconia loadings of 60 wt% (44 vol%) were accomplished with no evidence of constrained sintering. Novel processing techniques enhanced homogenization of the starting powders, thereby facilitating the elimination of agglomeration and constrained sintering. Samples were characterized using SEM, XRD, dilatometry and helium pycnometry. Vickers hardness testing was done to evaluate mechanical properties.
