Why is there no direct relationship between thermal conductivity and conductivity of ceramics?
The advanced production technology enables the fiber to distribute very evenly, and the paper thickness and bulk density can also be strictly controlled. Ceramic fibers have very low thermal conductivity. The thermal conductivity of ceramic fiber paper was measured by thermal flow method.
The concept of electrical conductivity in physics, in which the product of the quantity and the electric field intensity is equal to the conduction current density. For isotropic media, conductivity is scalar; for anisotropic media, conductivity is tensor. In ecology, conductivity is the ability to conduct current by means of a numerically expressed solution. The unit is expressed in SIEMENS per meter (S/m). The conductivity is simply the product of the measured conductivity (G) and the conductance cell constant (L/A). Here the L is the length of the liquid column between two plates and the A is the area of the plate. P l=l/ = sigma (1) definition or explanation for the reciprocal of resistivity conductivity. Sigma Rho =1/ (2): units in the international system of units, the conductivity of the unit is SIEMENS / m. (3) the physical meaning of conductivity is to indicate the conductivity of a substance.
Ceramic fiber paper is made from high purity refractory fiber and used in high temperature insulation.
