Ceramic Wear Components
Refractron Technologies Corp's Magnesia-partially Stabilized Zirconia (MgPSZ) is the optimum choice in ceramic wear components, liners, and sleeves where the traditional metal alloys fail. Sleeves and liners made with Refractron's Mg-PSZ Zirconia have superior abrasive resistance as compared to:
- carbon steel
- stainless steel
- Stellite Alloys 6
- Tungsten Carbide
In addition, zirconia is inert to virtually all acids, bases, solvents, and other corrosive slurries and fluids.
Refractron's MgPSZ zirconia ceramic wear components and liners will allow you to extend service life enabling you to improve operating efficiencies, reduce maintenance costs, and minimize downtime with less frequent repairs. Our zirconia is extremely strong and, has superior toughness along with excellent abrasion resistant qualities. Additionally we use a proprietary manufacturing process, starting with the highest purity raw materials that result in a chemically superior zirconia product as compared to the competition. This translates into superior chemical stability of the ceramic components in operation when subject to the corrosive liquids and slurries.
The range of dense structural ceramics using proprietary zirconia ceramics includes custom blended ceramic alloy powders, which are formed by isopressing or extrusion to meet customer specifications. These ceramic alloy components are used in extreme wear and corrosion applications in the chemical and petrochemical industry as well as components for healthcare applications.
Custom built ceramic wear component (liner and sleeve) sizes include: 2" OD up to 13" OD by up to 20" long and they are produced to order as fired blanks or as finished components with a variety of tolerances and finishes. Mg-PSZ liners provide better (6X) Abrasion Resistance than Tungsten Carbide along with better (3X) Impact Resistance than Silicon Carbide.
Proven applications for structural zirconia ceramic include:
- Chemicals (hot caustic, acids, solvents)
- Materials handling (abrasive fluids, suspensions)
- High velocity fluids
- Oil and gas (pipe spools, liners, sleeves)
- Pulp and paper
- All wear-prone and corrosive environments
In addition to liners and sleeves, the types of dense, structural ceramic components produced by Refractron include:
- valve components
- precision ceramic balls
- press tooling
- extrusion tooling and wear plates
Other specialty products include a range of porous ceramic filters, diffusers and adsorbent filter/drier cores for refrigeration applications, dispersion parts, vacuum chucks, inkpads and gas probes.
