Abstract
Thermal diffusivity, specific thermal capacity and thermal conductivity were measured by the xenon flash method to evaluate the thermal properties on 5 commercial kinds of temporary sealing cements.Thermal diffusivity of polycarboxylate temporary sealing cements were 0.2918 to 0.4444×10-2cm2s-1, and that of eugenol or nogenol temporary sealing cements were 0.1454 to 0.2574×10-2cm2s-1.The specific thermal capacity of polycarboxylate temporary sealing cements was 1.1558 to 1.5938Jg-1K-1, and that of eugenol or nogenol temporary sealing cements 0.7500 to 0.9004Jg-1K-1.The thermal conductivity of polycarboxylate temporary sealing cements was 1.0293 to 1.4616Wm-1K-1, and that of eugenol or nogenol temporary sealing cements 0.2497 to 0.3779Wm-1K-1.
