METHOD OF MEASURING HEAT CONDUCTANCE COEFFICIENT OF SOLID BODIES Russian patent published in 2006 - IPC G01N25/20

Abstract RU 2277235 C1

FIELD: testing of physical properties of materials.

SUBSTANCE: determination of heat conductance coefficient provides calculation of heat conductance coefficient from relation of λ=(C_v ¹Δx/a₀ ²xΔx/V_sound)m_ak_p=(C_v ¹V_sound/a₀ ²)m_ak_p, where C_v ¹is heat capacity of one atom in case the volume is constant; Δx is distance between closest atoms; m_a is atom weight of chemical element; k_p is reticular density coefficient of elementary cell of lattice; a₀ is period of lattice; V_sound is speed of transmission of oscillations (sound speed) in monocrystal.

EFFECT: reduced labor input; widened functional capabilities.
