FILLER AND COMPOSITE MATERIALS WITH ZIRCONIUM AND SILICA NANOPARTICLES

摘要

FIELD: chemistry.SUBSTANCE: invention relates to filler materials made of nanoparticles for use in composite materials, including dental composite materials. The filler materials contain clusters of silica and zirconium dioxide nanoparticles. The filler materials can be obtained by mixing a sol of silica nanoparticles with a sol of pre-formed crystalline particles of zirconium nano-oxide.EFFECT: filler materials provide the desired optical properties, such as opalescence, and are useful in dental compositions.25 cl, 4 tbl, 2 dwg
