The rheological properties of highly concentrated suspensions consisting of nanocrystalline powders of zirconium oxide with monoclinic, tetragonal, and cubic modification (stabilized at molar content of yttrium oxide 4 and 8%) and liquid UV-photocured monomers of different nature were studied. The dynamic viscosity of the suspensions with the highest filling to 32% by volume was equal to 3 Pa · sec at shear rate 10 sec – 1 and of the order of 1 Pa · sec at 100 sec – 1 and 20°C.
