Summary

The reaction of ZrO2 and H3PO4 to form ZrP2O7 was studied using thermogravimetric analysis (TGA), differential thermal analysis (DTA), x-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Results of the study led to a 50% reduction in the firing times of the ZrP2O7 matrix-based composites. Matrix infiltration between the fiber reinforcements was not improved by modified precursors. Brittle composites were associated with strong bonding between the fiber and the matrix, while firing in humid conditions led to strong, tough composites.
