Tetragonal ZrO 2 (t‐ZrO 2 ) nanoparticles (diameter: ca. 10 nm; BET‐specific surface area: 100 m 2 /g) are hydrothermally prepared via crystallization of 1,12‐diaminododecane (DADD)‐hydrous zirconia gels at 230°C for 3 days. The volume content of monoclinic phase is ca. 0.1. The surface‐adsorbed hydrocarbon layer (ca. 3 wt%) is observed by FTIR and TGA. They account for the formation of our t‐ZrO 2 nanoparticles with high‐phase purity.
