Synthesis of dental resins using diatomite and nano-sized SiO2 and TiO2
Progress in Natural Science: Materials International
The mechanical properties of dental composites were improved by porous diatomite and nano-sized silica (OX-50) used as co-fillers. The resin composites, filled with silanized OX-50 and silanized diatomite (40:60 wt/wt), presented the best flexural strength (133.1 MPa), elastic modulus (9.5 GPa) and Vickers microhardness (104.0 HV). Besides these, TiO 2 nanoparticles were introduced to tune the dental resin composites colours which were valued by the CIE-Lab system. The colour parameters (L n ,doi:10.1016/j.pnsc.2012.03.006 fatcat:wd4wzoqgdrgljbjnafygvlrzpq
