Refractron’s line of zirconia based products features Izory® and Izory® X magnesia partially stabilized zirconia (MgPSZ), yttria tetragonal zirconia polycrystal (YTZP) and specialty blends of zirconia and alumina. Our material portfolio allows us to offer our customers tailored solutions for applications that require strong, tough, wear and corrosion-resistant parts for severe processes below -200°C and as hot as 850°C.
Izory®, and other specialty zirconia materials, can be found on equipment drawing nonferrous wire, processing gas and chemicals, making aluminum cans and drilling oil. The specific components include: valve trim, precision balls, nozzles, tool and pump liners, dental blanks, plungers, blades, pistons, and drawing rolls.
Refractron designs and manufactures porous ceramics made from alumina (aluminum oxide), mullite and silicon carbide based formulations for a multitude of industries. This family of porous ceramics are often chosen in place of metals, rubber and plastics for their strength, chemical durability and stability at temperatures up to 1200°C (2192°F).
Porous ceramics are used for hundreds of applications but they are often categorized into wicks, filters, spargers or fine bubble diffusers. These products are used to aerate waste water, carbonate beverages, remove particulates from emissions, and recover precious minerals.
Refractron’s porous desiccant filter-drier cores are commonly referred to as core blocks, molded cores, filter cores, filter elements and desiccant blocks. These cores are typically a blend of molecular sieve, activated alumina, and activated carbon. Refractron features a patented Durasieve™ material that has excellent moisture capacity in a molded core configuration.
In addition to moisture removal, the cores also remove acid which comes from refrigerant breakdown. The core is an efficient particulate filter that removes scale, solder, dirt and debris that may be in the system to protect the compressor, capillary tubes, and valves.
