Abstract:

An addition of 15 Mol. calcium zirconate to strontium zirconate results in a material that has a modulus of rupture of about 27,800 psi as compared to strontium zirconate at 13,000 psi. This solid solution also exhibits the yield characteristics previously observed in strontium zirconate. Research has continued on the strengthening of strontium zirconate by various cation additions. The thermal expansion characteristics in the various crystallography axis have been carefully examined and it is concluded that sufficient anisotropy does not exist to cause microcracks in strontium zirconate. Strontium hafniate has been synthesized and is being examined. Author
