Does zirconia absorb microwaves?

Absorb. Zirconia absorbs microwaves, and zirconia generates heat in the microwave field. Zirconia, with chemical formula of ZrO2 _ 2 _ 2, is the main oxide of zirconium. Usually white, odorless and tasteless crystals, insoluble in water, hydrochloric acid and dilute sulfuric acid. Its chemical properties are inactive, with high melting point, high resistivity, high refractive index and low thermal expansion coefficient. It is an important high-temperature resistant material, ceramic insulating material and ceramic opacifier, and also the main raw material for artificial drilling.
