Technology for preparing zirconia-zirconium boride bilayer composite ceramic heating unit through slip casting method
The invention discloses a technology for preparing a zirconia-zirconium boride bilayer composite ceramic heating unit through a slip casting method. The heating unit is formed by a heating section, two transition sections and two wiring sections, each of the heating section and the transition sections is formed by an inner and outer bilayer ceramic structure, the inner core is ZrB2 matrix composite ceramic with a solid core structure, and the outer layer is ZrO2 matrix composite ceramic. The preparation technology of the heating unit comprises the steps of preparing a heating unit outer layer slip, preparing a heating unit inner layer slip, carrying out slip casting molding, demolding, and sintering. The heating unit prepared by adopting the technology for preparing the zirconia-zirconium boride bilayer composite ceramic heating unit through the slip casting method can provide a high temperature of 2000-2100DEG C in oxidation environment, and effectively overcomes the disadvantages of needing of a complex double-heating system of a zirconia heating unit in the use process and poor oxidation resistance of a zirconium diboride composite ceramic heating unit at a temperature of above 1800DEG C.
