Mullite-aluminum phosphate (3Al2O3-2SiO 2/AlPO4) laminated composites were fabricated by tape casting. A1PO4 had a density of 1.56 g/cm3, which corresponds to 61 % of theoretical density, and a bending strength of 1.5 MPa after sintering at 1600°C for 10 h. The aluminum phosphate functioned as a porous, weak, and chemically stable interphase which was able to deflect cracks in a laminated composite. To increase the strength of the weak interphase material, 10 and 30 vol% of mullite were added.
