Modelling material which contains (a) at least one radically polymerizable monomer, (b) at least one initiator for the radical polymerization and (c) at least one inert component. The inert component (c) is selected from phthalates, polyethylene glycols (PEG), polypropylene glycols (PPG), PEG-PPG copolymers, glycerol derivatives, ethoxylated or propoxylated glycerol, ethylenediamine tetrakispropoxylates and ethylenediamine tetrakisethoxylates. The material is suitable in particular for the production of models of dental restorations for investment casting processes.

This disclosure describes a process for preparing silica-coated calcium carbonate particles, involving the steps of preparing an aqueous carbonate slurry containing calcium carbonate particles, adding at least one silicate composition to the aqueous carbonate slurry to obtain a carbonate-silicate slurry, lowering a pH of the carbonate-silicate slurry by adding at least one acidic compound to obtain a pH-adjusted slurry containing the silica-coated calcium carbonate particles, and isolating the silica-coated calcium carbonate particles—in which at the adding of the acidic compound is controlled such that a final pH of the pH-adjusted slurry ranges from about 7 to about 10, and the silica-coated calcium carbonate particles include a porous coating having an average pore diameter ranging from 2 nm to 50 nm. This disclosure also describes articles and compositions containing the silica-coated calcium carbonate particles, as well as hollow silica spheres formed from the silica-coated calcium carbonate particles.

A dental liner and a manufacturing method therefor are disclosed. The dental liner is a dental liner for coupling feldspar porcelain and zirconia and includes: silicon dioxide; aluminum oxide; 1,4-butanediol for maintaining the moisture of the dental liner and preventing the generation of layers; and a zirconia powder for coupling the dental liner and zirconia by strengthening chemical bonding of the dental liner and zirconia.
