Durable And An Excellent Thermal Insulator – Prevent Mining Troubles With Zirconia Ceramics

Zircon is also used as a natural gemstone and may be processed to produce cubic zirconia, a synthetic gemstone and diamond simulant. Having a very high thermal expansion makes zirconia ceramics a great choice for joining ceramic and steel. Globally, the leading end uses for zircon were ceramics, zirconia, zirconium-based chemicals, refractories, foundry and casting applications; making them highly sought after by ceramic engineers and mineral processing equipment manufacturers. 


  • High thermal expansion 
  • Excellent thermal insulation/low thermal conductivity
  • Very high resistance to crack propagation, high fracture toughness
  • Conducts oxygen ions 
  • High thermal conductivity and strength

Various Properties Of Zirconia Oxide Ceramics 

Other properties that make zirconium oxide a good contender for the ceramic engineering industry are very low thermal conductivity and high strength.  In addition, some types of zirconium oxide ceramics can conduct oxygen ions. Components made from this material are significantly more expensive than components made of alumina ceramics. Zirconium also has great use in industries where corrosive agents are used extensively. The metal is used in the nuclear industry for cladding fuel elements since it has a low absorption cross-section for neutrons.  Zirconium oxide ceramics are used, among other applications, as tools for wire forming, as auxiliaries in welding processes, as materials for crowns and bridges in the dental industry, as insulating rings in thermal processes, and as oxygen measurement cells in lambda probes.

What Makes Zirconia As A Ceramic Sturdy?

Zirconia (ZrO2) is a ceramic material with adequate mechanical properties for manufacturing of medical devices. Zirconia stabilized with Y2O3 has the best properties for these applications. When a stress occurs on a ZrO2 surface, a crystalline modification opposes the propagation of cracks. Crack propagation is a scientific phenomenon on which scientific papers written reviews on. 

High Resistance To Crack Propagation

Under static loading, Zirconia has slow crack growth under static loading. Supposing the mechanisms responsible for cyclic crack growth were only related to irreversible slip, as occurs in metals, mechanical fatigue effects would not be expected to take place in ceramic materials. When compared to other advanced ceramic materials, zirconia has exceptional strength at room temperature. With cost-effective ceramic solutions for high-quality, they are great for managing cyclic load or any kind of thermal stress. It has the adequate chemical properties to be used for a wide array of applications.

Opt For Capital Steel Fabrications And Improve Your industry Practice

Industries such as coal and power plant, petroleum, and many others always look for better and cost-effective ways to improve their plant production and other crucial operations. One such way that helps them increase their efficiency and productivity is the introduction of capital steel fabrications  into their product manufacturing process. In the simplest term, steel fabrication is the method or technology used to build metal structures or equipment by cutting, bending or assembling processes. As steel is the most versatile industrial metal found on the planet so far, it offers unique and wide range of properties which make it a perfect metal to use in the production of different metal structure, from building and infrastructure to shipping, auto manufacture, and appliances. Stainless steel, due to its malleability and ductility, help industries reap the benefits that other metals fail to offer such as longer life, ability to sustain high temperature, protection against abras...

Advantages Of Using Ceramic Lined Pipes

Image
From generation of electric power to transportation of building materials, most operations of manufacturing and power industry involve the use of ceramic lined pipes. For transporting materials that have a hard abrasive nature, traditional steel pipes are not sufficient. Abrasion resistance capability is essential for dealing with such cases for preventing wear and tear. As compared to the conventional steel pipes used in thermal power plants and metallurgical applications, ceramic lined pipes offer far more optimal performance.  Based on the state-of-the-art technology, ceramic lined pipes are ideal for transporting raw coal powder, ash slag, hot flue gases, etc. The economic operation of these pipes not only prevents erosion but also protects the entire system from hidden dangers. Here are a few reasons why ceramic lined pipes are preferred over other types:- Anti-scaling properties During industrial operations, the inner layer of the pipes is bound to come into co...
