Types of Zirconia Crucibles

Calcia Stabilized Zirconia (CSZ) Crucibles

Calcia stabilized zirconia crucibles can overcome the difficulties posed by humid and rainy conditions because it is strong and resilient. It is an excellent material for generating sensors, instruments, probes, pumps, and fluid control systems due to its strong flexural and compressive strength. Furthermore, CSZ is more resistant to molecular water attack and can survive high temperatures, so it is employed when concerns about low-temperature degradation are present.

Fully-Stabilized Zirconia (FSZ) Crucibles

Yttrium, a rare earth metal that is silvery-white, ductile, and soft, stabilizes FSZ. It is utilized in high-temperature applications that require exceptional corrosion resistance, fracture toughness, and thermal shock resistance. Only oxygen ions may travel through FSZ, distinguishing it and making it useful for applications like active membranes. Zirconia changes from monoclinic to tetragonal to cubic, which increases its volume and causes fissures in the ceramic. The cubic polymorph can be stabilized and withstand a wide temperature range by adding yttrium.

Tetragonal Zirconia Polycrystalline (TZP) Crucibles

Tetragonal zirconia polycrystalline (TZP) ceramics exhibit exceptional fracture toughness and hardness at room temperature and corrosion resistance at high temperatures. They are the primary component in surgeries such as dental reconstruction and hip replacement. Fuel rod claddings in the industrial sector are coated with TZP to act as a thermal barrier. A robust, rigid material with an ideal microstructure is necessary for applications that call for the usage of TZP. TZP is similar to iron and iron-based alloys in thermal expansion coefficient. Because of its outstanding fracture toughness, it is known as ceramic steel.

Transformed, Toughened Zirconia (TTZ) Crucibles

TTZ is known as ceramic steel because it responds to stress with a strain pattern more like that of steel than a brittle ceramic material. Martensitic phase transition alters a material's stress state by raising tensile stress and acting against applied stress; it transforms and toughens zirconia ceramic.

Zirconia ceramics undergo a phase shift when tension is applied, raising the ceramic's volume and decreasing the local stress to prevent crack propagation. The procedure makes ceramic materials tougher. Ceramic knives, which are twice as hard as conventional steel knives and have ultra-sharp blades for accuracy and delicate cutting, are a typical application for TTZ.

How Zirconia Crucibles are Made


  • Mixing is a necessary step in creating the composite powder and can be done mechanically, in a multiphase solution, with a sol suspension, or with a sol-gel. The various techniques are chosen to guarantee a thorough blending of the composite powder; each has advantages.
  • Mechanical mixing is the simplest to grasp, but it offers the least assurance that the components will be distributed uniformly. Most of the time, mechanical mixing results in a mixture with a high porosity, which affects the zirconia material's mechanical properties.
  • Preparing a single-phase suspension with dispersed components is the initial stage in the multiphase suspension mixing process. The next step is identifying the conditions required for the particles in each phase to scatter uniformly. Finally, the typical flocculation conditions create uniformly mixed power. The flocculant absorbs the submicron flocs that result from mixing the suspended materials and fills the space between them.
  • Sol Suspension: Nano sol is a heterogeneous mixture that allows for the mixing of suspensions. The sol can be heated or agitated if the solid concentration is high to make high-mixed nanocomposite ceramics
  • Sol-gel is a method that creates solid materials from very small molecules by converting monomers into a colloidal solution, which serves as the gel's base. As a result, it generates a thoroughly-blended nanopowder.

Grinding and Packing

The mixture is blended with a stabilizer to create a ball, which is then squeezed between 60 MPa and 100 MPa under a small binder. Next, the zirconia oxide powder is made through compression, bringing the stabilizer particles into proximity.

Sintering Method

Sintering, which raises the stabilized zirconia powder to temperatures well over 1,000o C, is crucial for the quality and proper processing of zirconia ceramics. There are various techniques to sinter materials; the most popular methods include electric, high pressure, activation, and hot press.

Machining of Sintered Ceramics

Sintered zirconia ceramics must be machined to prepare the solidified material for various applications. Zirconia ceramics provide difficulties when machining mostly because of their remarkable hardness, which is relatively comparable to steel.

Uses of Zirconia Ceramics

Uses of Zirconia Ceramic in Dentistry

Tetragonal zirconia polycrystalline, magnesium stabilized, and ZTA are the three types of zirconia ceramic utilized in dentistry. Zirconia ceramics possess the qualities needed to function well for tooth restoration. In addition, since it does not induce allergic reactions, it is significantly superior to the metal dental materials of the middle of the 20th century in terms of aesthetics and strength. Zirconia is used for posts, crowns, bridges, and implants in dentistry.

Uses of Zirconia in Joints

Dense zirconia ceramics are employed for replacement joints, particularly for surfaces that can withstand wear. Zirconia ceramics may be polished to an exceedingly smooth finish and have mechanical advantages over metal alloys. As a bearing surface, the material's capacity to resist scratches is quite advantageous. Zirconia ceramic cutting blades work well for cutting membrane materials, including paper, aluminum, and steel.
