Carbon products and the physical properties of graphite products
2016/12/7??????view:
one. True density: refers to the volume of material, not including the pore volume per unit of material quality, commonly used method of measurement is the solvent replacement method, other methods are gas replacement method. X - ray diffraction method.
two. Density: the bulk density.
three. Porosity: sub-closed hole, open hole, three types of through-hole. four. Mechanical strength: compressive strength, tensile strength, flexural strength. Fives. Elastic modulus: the elastic deformation within the material, the ratio of stress and strain is called elastic modulus.
In this case,
six. Resistivity: Influencing factors: 1. Raw material, 2. Finished final heat treatment temperature, 3 finished product density, 4 resistivity and test temperature, 5. Graphite products of resistivity anisotropy.
In this case,
Seven. Thermal conductivity: the material sample in the unit temperature gradient, the unit area per unit time in the heat transfer.
