In demanding high-temperature industrial settings, material performance often determines production efficiency, product quality, and operational viability. Equipment reliability under extreme thermal conditions remains a persistent challenge across multiple sectors. ZIRCAR Ceramics, a global leader in specialty ceramic materials, has developed a comprehensive range of high-performance ceramic fiberboards designed to address these challenges.

Engineered for Extreme Conditions

The ZIRCAR Ceramics fiberboard series represents the convergence of advanced materials science and precision manufacturing. Engineered to withstand temperatures ranging from 1260°C to 1700°C, these solutions provide exceptional thermal insulation, refractory properties, and structural support for industrial furnaces, heat treatment equipment, kilns, and other high-temperature processes.

Material Innovations and Technical Specifications

High-Purity Alumina Series

The alumina-based products demonstrate superior thermal stability and insulation characteristics. The AL-25 and AL-28 variants withstand continuous temperatures up to 1700°C and 1800°C respectively, while specialized formulations like ALC and ALC-AA offer enhanced resistance to corrosive or reducing atmospheres. The ZAL series features exceptional high-temperature strength and dimensional stability, with the ZAL-45 variant combining high density with fine open-cell structure for both strength and low thermal conductivity.

Alumina-Silica Compositions

These formulations balance performance with cost-effectiveness. The AXL model utilizes refractory ceramic fibers and colloidal silica binders to achieve 1260°C thermal resistance, while the Z-500 variant incorporates specially treated fibers and inorganic binders for applications below 1000°C.

Microporous Insulation Technology

The MICROSIL product line demonstrates thermal insulation performance an order of magnitude superior to conventional ceramic fiber materials, maintaining effectiveness up to 950°C.

Soluble-Fiber Solutions

The UNIFORM B1 variant provides rigid, medium-density insulation using soluble fibers and inorganic binders, suitable for applications requiring environmentally conscious materials up to 1180°C.
