Abstract
Official abstract text for this publication.
[Problem] To provide a dental porcelain paste that can maintain a constant paste property even during long-term storage, and that hardly generates carbonization and bubbles during firing even in the case of containing organic components. [Solution] To provide a dental porcelain paste for preparing a dental prosthesis device, comprising (a) base material glass having an average particle diameter D50 of 1 to 20 μm, (b) hydrophobized fine particle silica having an average primary particle diameter of 1 to 50 nm, (c) organic solvent having a boiling point of 100 to 300° C., and (d) inorganic salt.
First claim
Opening claim text (preview).
What is claimed is: 1 . A dental porcelain paste for preparing a dental prosthesis device, comprising (a) base material glass having an average particle diameter D50 of 1 to 20 μm, (b) hydrophobized fine particle silica having an average primary particle diameter of 1 to 50 nm, (c) organic solvent having a boiling point of 100 to 300° C., and (d) inorganic salt. 2 . The dental porcelain paste according to claim 1 , wherein the dental porcelain paste comprises, with respect to 100 parts by mass of the (a) base material glass, 1 to 15 parts by mass of the (b) hydrophobized fine particle silica, 15 to 90 parts by mass of the (c) organic solvent, and 0.05 to 1.0 parts by mass of the (d) inorganic salt. 3 . The dental porcelain paste according to claim 1 , wherein the dental porcelain paste further comprises (e) coloring material and/or (f) fluorescent material which are inorganic materials. 4 . The dental porcelain paste according to claim 2 , wherein the dental porcelain paste further comprises (e) coloring material and/or (f) fluorescent material which are inorganic materials. 5 . The dental porcelain paste according to claim 1 , wherein a maximum particle diameter D100 of the (a) base material glass is 200 μm or less. 6 . The dental porcelain paste according to claim 2 , wherein a maximum particle diameter D100 of the (a) base material glass is 200 μm or less. 7 . The dental porcelain paste according to claim 3 , wherein a maximum particle diameter D100 of the (a) base material glass is 200 μm or less. 8 . The dental porcelain paste according to claim 4 , wherein a maximum particle diameter D100 of the (a) base material glass is 200 μm or less.
