Abstract
ABSTRACTTo synthesize a novel purple zirconia ceramic, Nd2O3 was introduced as a colorant to improve the mechanical properties and color properties of purple ceramics. It was found that causes the color and mechanical properties to obey different rules. With increases Nd2O3, the color of purple zirconia ceramics is gradually deepened, corresponding and the negative influence on hardness. In this case, the optimal comprehensive properties of zirconia ceramics can be found at the 4 mol% Nd−2.5YSZ, at which purple zirconia ceramics with an even, continuously adjustable color and positive high-temperature stability can be obtained and used as a new type of environmentally friendly colorful ceramics. Based on their good mechanical and optical properties, these purple ceramics can be widely used in high-tech fields such as mobile phone backplanes, optoelectronics and high-end decorative materials.
Highlights
An indispensable structural and functional material with excellent physical and chemical properties, zirconia is recognized as an inorganic non-metallic material featuring high-temperature resistance, wear resistance and corrosion resistance [1]

The mechanical properties are excellent, the colors are diverse, and the needs of daily applications are met. Problems such as unitary hues, poor stability at high temperatures, uneven color rendering and high energy consumption still exist under the circumstance of a handful of development efforts conducted on shades of purple zirconia ceramics
Summary
An indispensable structural and functional material with excellent physical and chemical properties, zirconia is recognized as an inorganic non-metallic material featuring high-temperature resistance, wear resistance and corrosion resistance [1]. Purple Nd: YAG ceramics with high transparency can be obtained, For example, by doping YAG with neodymium oxide Due to this high synthesis temperatures and poor mechanical properties, corresponding applications in structural ceramics may result in failure because of high energy consumption and processing requirements [6,7,8]. As no requirements are made concerning the sintering atmosphere and pressure, simple production processes featuring environmental protection and energy savings can be developed for ceramic materials Based these findings, continuously adjustable purple zirconia ceramics can be prepared with excellent mechanical properties guaranteed [1,9]
