Thermal Conductivity

A material property that quantifies the rate at which heat is conducted through the material; usually expressed as heat flux density per unit temperature gradient (k in Fourier's law, q = -k ∇T).

An intrinsic material property k (units W·m⁻¹·K⁻¹) that quantifies the rate of conductive heat transfer through a homogeneous medium under a temperature gradient, appearing in Fourier's law where heat flux density equals -k times the temperature gradient.

The material property quantifying the rate at which heat is transmitted through a unit thickness of dental material per unit temperature gradient, typically expressed in W·m−1·K−1 for steady‑state conduction.
