Cordierite ceramic load bearing board for MnZn ferrite sintering
The invention discloses a cordierite ceramic load bearing board for MnZn ferrite sintering. The cordierite ceramic load bearing board comprises a base body and a magnetic oxide coating. Cordierite, albite, potassium feldspar, magnesium aluminate spinel, yttrium oxide and electric-molten mullite are taken as main raw materials, and at the same time, additives such as alumina micro powder, metallic silicon powder, aluminum nitride, copper nanoparticles, silica sol, a surfactant and steel fiber are added, so that the physical and chemical properties of the base board are further improved; and as the magnetic oxide coating is prepared with the combination of zirconium oxide and ferric oxide gel, reaction of the magnetic oxide and the base board can be prevented to the maximum extent. The normal temperature pressure resistance of the ceramic load bearing board disclosed by the invention is greater than 69MPa, the apparent porosity is greater than or equal to 23%, and the volume density is greater than or equal to 3.9g/cm<3>.
