High alumina brick is a kind of refractory material, and the main component of this refractory brick is Al2O3.
The heat conduction of high alumina brick consists of phonon heat conduction and photon heat conduction, and the heat transfer of the pore is divided into convection and radiation.
The influence of porosity on heat transfer in high alumina brick depends on the number and size of pores, the degree of connectivity and the transmittance of high alumina bricks.
We can also supply the high quality refractory brick, sic heating element etc. If you need, welcome to contact us.
