Pre-Formed Refractory Lining Solutions Engineered for Your Exact Requirements

When standard brick configurations can’t meet your unique furnace geometry or application requirements, Zircoa custom shapes provide the precise refractory lining solutions you need. Our pre-formed, pre-sintered custom refractory components are engineered to your exact specifications, offering superior forming methods and optimized physical properties for demanding applications.

These advanced custom shapes serve as high-performance replacements for traditional burner blocks while expanding capabilities far beyond glass furnaces into carbon black production, electronics manufacturing, energy systems, and medical applications where precision and reliability are critical. With Zircoa refractory lining, either Calcia, Yttria, or Magnesia-stabilized zirconium oxide compositions help extend burner block life, withstand high temperatures and contaminants present in fuel oil.
