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 can be used as Jar (Yttria Stabilized Zirconia crucible) cause of the following properties High strength, high fracture toughness, high hardness and high density, stability, wear resistance, corrosion resistance, high temperature resistance.
Zirconia (ZrO2) crucibles are great refractory and insulating containers. They have a clean melt at temperatures above 1900°C and above and are specially manufactured for melting superalloys and precious metals. They also have excellent chemical inertness, superior thermal shock resistance to temperatures reaching up to 2200°C, and good corrosion resistance to acids and alkalis.

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.
Applications of Yttria Stabilized Zirconia Crucible
–two types of them are divided as follows:
Refractory grade zirconia crucible, Density: 4.5g/cc, has micropores inside, also named a semi-ceramic crucible. It exhibits corrosion resistance performance of zirconia, is stable in the oxidizing and reducing atmosphere, and it is very resistant to many solutions and slag. At the same time, it has the thermal shock resistance of refractory materials, which greatly improves the change of temperature gradient during use, and is widely used in the smelting of platinum and other rare precious metals. Three main size of this type: 250ml, 5.0mmOD x 8.0mm H, 6.8mmOD x 4.0mm H. The last one is used as a thermal analysis crucible; it solves the analysis for materials that will react with alumina crucible at a high temperature
Ceramic grade zirconia crucible, density: 6.0g/cc, fully densified, and no pores. High-purity ceramic zirconia crucible is white, it will show yellow or grey if the purity is lower. It has stable chemical properties, except for sulfuric acid and hydrogen sulfuric acid, it has good stability to other acids, alkalis and alkali melts, glass melts and molten metals, low thermal conductivity, good thermal stability, and high temperature creep. The thermal conductivity is low, and the coefficient of thermal expansion is close to that of metal materials. It is an important structural ceramic material.
Zirconium Oxide Crucibles deliver cleaner melts at temperatures up to 1900°C and beyond. They are engineered for the melting of superalloys and precious metals and deliver heat-up and cool-down schedules that keep your foundry productive. They are widely used in:
Yttria Stabilized Zirconia / YSZ grinding jars are used to grind materials into extremely fine powder for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. –Zirconia jars and Zirconia balls are strong and have good abrasion resistance, which prevents mixing with other impurities while ball mill grinding.

Packing of Yttria Stabilized Zirconia Crucible
Standard Packing:
Sealed bags in carton boxes. Special package is available on request.
As a ceramic material, YSZ is quite fragile in a lot of cases. The YSZ Crucible are usually held in plastic bags by vacuum, and protected with heavy foam.
ATTs’ YSZ Crucible is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
