http://www.jldceramics.com/zirconia-ceramics/ Zirconia ceramics have high melting and boiling points, high hardness, insulators at room temperature, and electrical conductivity at high temperatures. The production process includes dry pressing molding, isostatic pressing molding, grouting molding, hot die casting molding, flow casting molding, injection molding, plastic extrusion molding, colloidal solidification molding, etc. Among them, injection molding and dry pressing are the most widely used. The sintering methods available for zirconia ceramics usually include 鈶碢ressureless sintering 鈶礖ot pressing sintering and reactive hot pressing sintering 鈶禜ot isostatic pressing (HIP) 鈶稭icrowave sintering 鈶窾ltra-high pressure sintering 鈶筍park plasma sintering (SPS) 鈶篒n-situ compression molding and sintering, etc. It is often based on pressureless sintering. Application In terms of structural ceramics, zirconia ceramics are widely used in the field of structural ceramics due to their high toughness, high bending strength and high wear resistance, excellent thermal insulation properties, and thermal expansion coefficient close to steel. Mainly include: Y-TZP grinding balls, dispersion and grinding media, nozzles, ball valve seats, zirconia molds, micro fan shafts, optical fiber pins, optical fiber sleeves, wire drawing dies and cutting tools, wear-resistant knives, clothing buttons, Watch cases and straps, bracelets and pendants, ball bearings, light golf clubs and other room temperature wear-resistant parts. In terms of functional ceramics, its excellent high temperature resistance is used as induction heating tubes, refractory materials, and heating elements. Zirconia ceramics have sensitive electrical performance parameters and are mainly used in the fields of oxygen sensors, solid oxide fuel cells (Solid Oxide Fuel Cell, SOFC) and high temperature heating elements. In addition, zirconia is widely used in thermal barrier coatings, catalyst carriers, medical treatment, health care, refractory materials, textiles and other fields.
