Способы получения пористой керамики на основе стабилизированного диоксида циркония

Abstract

Porous ceramics obtained by different methods: the most common method is method which using a pore-forming additive in the form of burnout charcoal and structural leaching method chemically unstable phase with acid or alkali. As a result of using a burnable additives as a blowing agent was prepared with a bi-modal pore structure distribution of pores (macropores and mesopores) with an average pore size of about 1000 nm, the open porosity of 45 %. Using the method of structural leaching obtained channel pores (meso-pores) with a diameter of 10 – 50 nm, an open porosity of 35 %.
