Thermal expansion coefficient and specific heat capacity of boron carbide

Release time:2021/03/11 Author: Meiqi

The melting point of boron carbide is 2450℃, the boiling point is 3000℃, the thermal expansion coefficient is 5.73×10-6/℃(28-1770℃), and the specific heat capacity is calculated by the formula (11) :

C = 22.99 + 5.40 x 10-3 t - 10.72-2 x 105 t (11)
