YSZ (ytria-stabilized Zirconia)<\/a><\/span><\/strong> is a ceramic material composed of zirconium dioxide (ZrO\u2082) stabilized by yttria (y\u2082O\u2083). By adding yttria, the phase transition temperature range of zirconium dioxide is changed to produce cubic and tetragonal crystals that are stable at room temperature. Due to the stabilization process, it has excellent mechanical properties, thermal stability and chemical stability, so it has been widely used in many fields.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
