Leucite content of selected dental porcelains [PDF]

Journal of Biomedical Materials Research, 1994
AbstractLeucite is a major crystalline component of dental porcelains. The presence of tetragonal leucite in dental porcelains increases their coefficients of thermal expansion due to its high coefficient of thermal expansion (20–25 × 10−6/°C). This is particularly useful for those porcelains designed for bonding to precious metals and nickel alloys ...
