Abstract : The compositions in Table 1 were sintered as reported in the previous progress report. Sintered dimension were measured; shrinkages were calculated. Densities were measured by the liquid immersion technique. The results are tabulated in Table 2. The results of X-ray diffraction studies are given in Table 3. Preliminary microstructural studies showed the presence of fibrous microstructures in samples of compositions D and E. Further microstructural analysis is being carried out on samples having compositions C, D, E, and F.
