The preparation of dental glass-ceramic composites with controlled fraction of leucite crystals
Original language description
This work is dealing with synthesis of leucite powder, which can be used for the preparation of dental glass-ceramic composites by subsequent thermal treatment. Newly developed procedure is based on preparation of dental raw material as a mixture of twoseparate compounds: the crystalline leucite powder prepared at relatively low temperature and a commercial matrix powder. Hydrothermal synthesis of tetragonal leucite particles (KAlSi2O6) with the average size of about 3 ?m was developed in our laboratory. The leucite dental raw material was prepared by mixing of 20 wt.% of synthetic tetragonal leucite with commercial matrix. Dental composites were prepared from the dental raw material by uniaxial pressing and firing up to 960°C. Dilatometric measurements confirmed that the coefficient of thermal expansion increased by 32 % when 20 wt.% of the tetragonal leucite was added into the basic matrix. In addition, it was showed that the synthesized leucite powder was suitable for the preparati

Příprava kompozitu dentální sklo-keramiky s řízeným podílem leucitových krystalů
Czech description
Práce se zabývá syntézou leucitového prášku, jenž je možné použít pro přípravu kompozitu dentální sklo-keramiky po následné tepelné úpravě. Nově vyvinutý postup je založen na přípravě dentální suroviny ve formě směsi oddělených složek: prášku krystalického leucitu připraveného za relativně nízké teploty a prášku komerční matrice. Hydrotermální syntéza částic tetragonálního leucitu s průměrnou velikostí 3 ?m byla vyvinuta v naší laboratoři.
