ZrO 2 microspheres were prepared with an improved internal gelation process without cooling the precursor solution. The stability of broth for has been systematically investigated, and results show that preparation storage temperature, concentration NO 3 − urea in have important effects on broth. Through optimizing formulation can be stable 14 h at 25°C. ceramic uniform size good sphericity, a density 5.87 g/cm .
