LONGLY provides a multitude of zirconia products including balls, plates, tubes, rods and etc. by adopting magnesia, calcia or yttria stabilized zirconia powder as raw material through dry pressing, isostatic pressing and hot pressing. The fine grain size allows for extremely smooth surfaces. Meanwhile Zirconia has low thermal conductivity and is an oxygen-ion conductor above 600°C, which could be used as oxygen sensors and high temperature fuel cells.

     Compared with alumina ceramics, they have higher abrasion resistance, flexibility, chemical stability, and corrosion resistance. LONGLY’s Zirconia products are high temperature resistant, hard, insulated, wear resistant, anti-split, high pressure resistant ,  particularly tough and without use of any auxiliary lubricant, which are most suitable for harsh environment. We could manufacture and machine various precision ceramic structural parts according to customer request. Main products consist of grinding ball, nozzle, ball valve, ball seat, zirconia molds, optical fiber base pin, optical fiber ferrule, wire drawing film, sealing ring and other wear-resistant parts, which are widely used in metallurgical, electrical, electronic, automotive, pneumatic components, machinery, chemical, textile and other fields.
