Every application is unique and deserves a unique solution – whether 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 uptime, 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 the 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 leader in andalusite production. Predictable thermal expansion, excellent creep resistance and refractoriness under load, high thermal shock resistance as well as a terrific resistance to chemical attack and slag and metal penetration come together in this naturally occurring crystal. Pioneered commercially at our plant in Glomel, France, and supported by South Africa, our range including Durandal, Purusite, Randalusite and Kerphalite is unmatched on the market today.
Andalusite run of mine – used for standard refractory applications especially shaped refractory.
Andalusite premium grades – especially designed for high quality refractories such as glass or kiln furniture.
Andalusite sieved milled grades – ideal to reinforce the refractory matrix from RCC to ULCC.

Molochite™ with its excellent thermal stability and even particle size distribution is a particularly suitable ingredient for castables, mouldables and ramming and gunning mixes.
Imerys Refractory Minerals is the world’s leading producer of calcined products for the refractory industry. Our brand portfolio is comprised of the well-known Mulcoa® and Super Ecca Chamotte lines.
Super Ecca Chamotte is our range of super-duty chamotte materials for general purpose refractory applications. These products are available as sized or run of kiln for mixes where 42-44% alumina calcinates are required.
Technical datasheet is available on demand.
Mulcoa is a mainstay of refractory production, wherever volume stability, resistance to carbon monoxide attack and all-round performance are required.
Teco-Sil® fused silica products are specially engineered grains and powders designed for refractory use.
Fused silica is extremely insulative material with very low thermal conductivity and with its good thermal shock resistance it is often used in flow control/continuous casting applications (for steel making) and glass rolls.
