Every application is unique and deserves a unique solution – be it abrasion, thermal shock, hot structural loading, alkali attack, reducing atmospheres or liquid metal contact, we understand that your products cannot be characterized by alumina content and cold compressive strength alone.
With any refractory formulation the ability to obtain the correct blend of performance and price is a moving target, with customer’s needs changing based on not just the application itself, but the desired internal metrics of any organization, whether up time, installed price or total cost of ownership. IMERYS REFRACTORY MINERALS’ ability to offer a range of materials means that within the portfolio we will have an option that gives increased flexibility needed to deliver the solution your customer wants.
Once you have the right material, consistency and dependability become the critical factors. As the design of modern refractory materials is more and more technical and complex, the presence of known, consistent and reliable components is key to the repeatability during installation that customers and installers demand.
Imerys Refractory Minerals is the world’s leading producer of calcined products for the refractory industry.
Mulcoa® is a mainstay of refractory production, where volume stability, resistance to carbon monoxide attack and all-round performance are required.
Imerys Refractory Minerals is the world’s leading producer of andalusite.
Thermal shock resistance, volume stability and high temperature load strength uniquely come together in this naturally occurring crystal. Pioneered commercially at our plant in Glomel, and supported by South Africa our range including Durandal™, Purusite™, Randalusite™ and Kerphalite™ is are unmatched in the market today.
Andalusite run of mine – is used for standard refractory applications especially shaped refractory.
Andalusite premium grades – especially designed for very clean refractories such as glass or kiln furniture.
Andalusite sieved milled grades – is ideal to reinforce the refractory matrix from RCC to ULCC.
Molochite™, with its excellent thermal stability and regular particle size distribution, is a particularly suitable ingredient for castables, moldables and ramming and gunning mixes where 42-44% alumina calcinates are required.
Teco-Sil® fused silica products are specially engineered grains and powders designed for refractory use.
Teco-Sil is an extremely insulative material with very low thermal conductivity and good thermal shock resistance. It is often used in flow control/continuous casting applications (for steelmaking) and glass rolls.
For standard grades:
At Imerys Refractory Minerals we produce, process and sell a full range of high alumina products. Our high alumina range is processed, sized and milled in the USA at our plant in Andersonville, GA.
We also market fused alumina oxides, fused mullite and bubble alumina produced by Imerys Fused Minerals
Our WFA (white fused alumina) and spinel are available in various sizes.
Our individual technical datasheets are available upon request.
Imerys Refractory Minerals offer the famous KT-Clays to be used either as a binder for refractory brick production, or as additives to improve plastic behavior during installation.
