Refractron Technologies Corp. is a leading manufacturer of technical ceramics. Products include both controlled porosity and densely structured ceramics designed to meet requirements specified by our customers for durability, chemical, corrosion and wear resistance, toughness, and density. The range of dense, structural ceramics using proprietary zirconia ceramics includes custom blended ceramic alloy powders formed by isopressing or extrusion to meet customer specifications. Refractron’s zirconia is offered in two materials Magnesia Partially Stabilized Zirconia, Mg-PSZ and Yttria Tetragonal Zirconia Polycrystal, Y-TZP. Refractron’s structural ceramic zirconia materials provide excellent erosion, corrosion and abrasion resistance along with temperature resistance, fracture toughness and strength. Numerous applications for these materials are in the chemical and petrochemical industry providing economic payback in the way of reduced maintenance and down time. Zirconia is also used for components in healthcare and dental applications. The types of dense, structural ceramic components produced by Refractron include: valve components, pump liners, plugs, sleeves, pistons, precision ceramic balls, spools, press tooling, dental blanks and extrusion tooling.
The range of Refractron porous ceramics include monolithic and membrane components made from aluminum oxide and silicon carbide. The strong, uniform porous ceramic has 40-50% open porosity with a tortuous pore structure and is available in pore sizes ranging from 0.25 to 90 microns. The types of porous ceramic products include membrane and monolithic tubes, discs, plates and other components where tightly controlled pore size and porosity is critical. Filtration is a common application where porous ceramic is used for catalyst recovery, hot gas, liquid backwash, solvent filtration, coalescing and solids recovery in chemical process, water and mining industries. Diffusion or sparging using porous ceramics to produce fine bubbles is another typical application as high gas transfer efficiencies are achieved with the fine, uniform pore structure. Other specialty porous ceramic products include a range of wicking & dispersion parts, vacuum chucks, fluid bed plates, inkpads, gas probes and a range of adsorbent filter/drier cores for refrigeration applications.
