摘要：

Zirconia can be prepared to produce either tetragonal phase or predominantly monoclinic phase upon calcination at 500-degrees-C. The precursors for each phase of zirconias was treated with 1N H2SO4 to produce a sulfated material. The results reveal that sulfation causes the tetragonal phase to be formed for both types of zirconia contrary to the data before sulfation, and sulfation increases the crystallization exotherm by 150-degrees-C.
