Vulcan Refractories manufactures hybrid mullite-silicon carbide refractories for demanding industrial applications where thermal conductivity, mechanical strength, and durability must work together.
By combining carefully controlled proportions of mullite and silicon carbide, these advanced refractory materials deliver tailored thermal performance while maintaining exceptional structural integrity. Manufactured to client specification, they are suitable for a wide range of high-temperature processes across the UK and internationally.
It combines the benefits of two proven refractory materials into a single engineered solution.
Silicon carbide provides excellent thermal conductivity, abrasion resistance, and durability, while mullite contributes thermal stability, resistance to thermal shock, and structural strength. By carefully controlling the ratio of each material, we can tailor the thermal characteristics without compromising mechanical performance.
This makes hybrid refractories an excellent choice for applications requiring both efficient heat management and long service life.
Our hybrid mullite-silicon carbide refractories offer:
Each product is manufactured to meet the specific thermal and mechanical requirements of the application.

They are engineered refractory materials that combine mullite and silicon carbide to provide a balance of thermal conductivity, mechanical strength, abrasion resistance, and thermal shock performance.
Hybrid materials allow thermal conductivity to be tailored while maintaining excellent mechanical durability, making them suitable for a wider range of industrial applications than single-material refractories.
Typical applications include glass manufacturing, ceramics, foundries, heat treatment, and energy-from-waste plants.
Yes. By altering the ratio of mullite to silicon carbide, the thermal properties can be tailored to suit the specific operating conditions of the application.
Yes. Vulcan manufactures both standard and bespoke refractory products to client specification, ensuring each solution is optimised for the customer’s process.
