Embodiment Construction
[0039] Each parameter measuring method in the implementation of the present invention and ratio is:
[0040] 1. Use a laser thermal conductivity meter to measure the thermal conductivity of the material.
[0041] 2. Use DSC to test the latent heat value of the phase change of the material.
[0042] 3. Use DSC to test the specific heat capacity of the material.
[0043] 4. Use a spectrophotometer to test the spectral absorptivity of the material.
[0044] Below with example, the embodiment of the present invention is described further:
[0045] The first step: preparation of biomimetic silicon carbide ceramic skeleton.
[0046] Cut the wood into a cuboid with a length of 70mm, a width of 50mm, and a thickness of 30mm. The cut wood is dried in a drying oven at 70°C for 2-3 days. Place in a tube furnace with nitrogen protection atmosphere, raise the temperature to 500°C at a heating rate of 0.5°C / min, and then raise the temperature to 900~1100°C at a heating rate of 1°C / min ...
