Nano zirconia is a multifunctional material with various unique physical and chemical properties, which leads to its widespread application in multiple fields. Its main uses include: Toughened ceramics and refractory materials. The high temperature resistance, good chemical stability, and self-lubricating properties of nano zirconia make it an ideal choice for manufacturing high-temperature refractory materials and reinforcing plastic frameworks. Oxygen sensors and catalytic fields. Due to its sensitivity to oxygen concentration differences, nano zirconia is used for oxygen sensors, and due to its high oxygen ion conductivity and conductivity characteristics, it is also used for electrode manufacturing in high-performance solid state batteries. Lithium battery materials. Doping nano zirconia into the positive electrode material of lithium batteries can improve the cycling and rate performance of the battery. Biomedical. Due to its biocompatibility and controllable drug release performance, nano zirconia has been applied in fields such as drug delivery systems, tissue regeneration, and biological imaging. Ceramic manufacturing. Used for manufacturing advanced ceramic products such as high-strength structural ceramics, thermal barrier coatings, and solid oxide fuel cells. Functional structural ceramics field. Due to its high strength and toughness, as well as its acidic, alkaline, oxidizing, and reducing properties, nano zirconia has important applications in the field of catalysis. Wear resistant products. Such as mill lining, cutting tools, drawing dies, etc. Bioceramics and artificial gemstones. Used for electronic ceramics, bioceramics, and grinding materials, etc. In addition, nano zirconia is also widely used in lubricant additives and electrode manufacturing of high-performance solid state batteries.
