Ultimate Customization with Castable Refractory Materials for On-Site Forming

When your application demands another level of customization and flexibility, Zircoa castable refractory materials provide the solution. These loose, wet-form materials allow you to create custom shapes, repairs, and complex geometries directly at your facility, offering unmatched design freedom for unique furnace configurations and field applications.

Unlike pre-fired or pre-sintered products, our castable refractory materials cure and develop their properties in place, enabling seamless installations and perfect conformity to any geometry. Zircoa provides the specialized “cement” formulations along with expert guidance on proper mixing, application, curing, and heat treatment procedures.

Our selective approach ensures you receive exactly the right castable refractory composition for your specific application, backed by our decades of expertise in refractory material science. Learn more below, or reach out to our team for more information.
