## Abstract Thermal conductivities were determined for five commercial composite restorative materials, one composite crown and bridge cement, two cavity βbases,β and poly(methyl methacrylate). In addition, the effect on thermal conductivity of concentration and type for five resinβreinforcing fill
Thermal conductivity data are presented for several samples: Gd2 (SO4) 3 8H2 0 pressed powders with and without copper fibres, pressed powders of NaCI and KCI, cloth base phenolic sheet, epoxy resin-bonded glass fibre laminate, and AGO T graphite in the presance of helium gas. Measurements on all sa
