Product Code :
Yttria Stabilized Zirconia (YTZP) is the strongest ceramic material we offer. YTZP is a purely tetragonal phase, fine grain material. This material offers the highest flexural strength of all Zirconia based materials. YTZP exhibits a trait called transformation toughening which allows it to resist crack propagation. Applied stress, magnified by the stress concentration at a crack tip, can cause the tetragonal phase to convert to monoclinic, with the associated volume expansion. This phase transformation can then put the crack into compression, retarding its growth, and enhancing the fracture toughness. This mechanism significantly extends the reliability and lifetime of products made with stabilized zirconia. YTZP is well suited to replacing metals due to its extremely high strength and toughness, it also offers far higher resistance to chemicals and superior erosion resistance.
Zirconia Ceramic Tube (Yttria Stabilized Zirconia Tube, YSZ Tube) has the advantages of super hardness, high wear-resisting, good corrosion resistance, and high-temperature tolerance, high strength, high mechanical strength, and good chemical stability, polishing surface, and so on.

Zirconia Machining
Zirconia can be machined in green, biscuit, or fully dense states. While in the green or biscuit form, it can be machined relatively easily into complex geometries. However, the sintering process that is required to fully densify the material causes the zirconia body to shrink approximately 20%. This shrinkage means that it is impossible to hold very tight tolerances when machining zirconia pre-sintering. In order to achieve very tight tolerances, the fully sintered material must be machined/ground with diamond tools. In this manufacturing process, a very precise diamond coated tool/wheel is used to abrade away the material until the desired form is created. Due to the inherent toughness and hardness of the material, this can be a time consuming and costly process.
