Coefficient of thermal expansion of zinc
WebMoreover, the use of these diffuse reflectors can offset the negative effect of the optical losses in the case of glazed PV-T collectors, achieving higher electrical and thermal efficiency. Thermal efficiencies of up to 80% and 75% for water and air extraction modes respectively have been reported [ 71, 73 ]. Web1 day ago · Within a temperature range of 25–400 °C cordierite coatings have a thermal expansion coefficient of 3.21*10 −6 K −1. Above, the softening point of amorphous cordierite a deformation and bending of the test specimen is reported due to the pressure of the dilatometer push rod. This yields to a decrease of the measured CTE [4], [5].
