With the increasing global industrial demand for high-temperature energy efficiency and environmental protection, high-temperature resistant and corrosion-resistant insulation materials have become a focal point in the industry. To address this, Long Keter has officially launched a new generation of high-performance zirconium-containing ceramic fiber blankets, dedicated to providing reliable solutions for high-temperature and highly corrosive environments in metallurgy, petrochemicals, power generation, and other industries.
What is a zirconium-containing ceramic fiber blanket?
Zirconium-containing ceramic fiber blanket, also known as zirconia-based ceramic fiber blanket, is a high-end refractory insulation material made from high-quality aluminum-silicate fibers with the innovative addition of zirconium oxide (ZrO₂). The incorporation of zirconium oxide significantly enhances the material's high-temperature resistance, thermal stability, and chemical erosion resistance, allowing it to withstand long-term use at temperatures up to 1425°C. This makes it one of the most superior-performing categories of ceramic fiber blankets currently available.

Classification and Selection of Ceramic Fiber Blankets

In the market, ceramic fiber blankets are primarily categorized into six types based on their temperature resistance, from low to high:
Ordinary Type, Standard Type, High-Purity Type, High-Alumina Type, Zirconia-Alumina Type, and Zirconium-Containing Type.

Among these, zirconium-containing ceramic fiber blankets, with their exceptional temperature adaptability and corrosion resistance, have become the preferred material for extreme working conditions. If your projects involve high-temperature furnaces, chemical equipment, or new energy thermal management, zirconium-containing ceramic fiber blankets will provide robust support for system safety and energy efficiency.

Core Advantages of Long Keter Zirconium-Containing Ceramic Fiber Blankets

• Exceptional High-Temperature Resistance: Withstands temperatures up to 1425°C, making it suitable for prolonged high-temperature environments.

• Strong Corrosion Resistance: The zirconium oxide component effectively resists erosion from acidic gases and molten slag, extending equipment lifespan.

• High Thermal Stability: Maintains structural integrity under rapid heating or cooling conditions, minimizing cracking and deformation.

• Energy-Efficient and Eco-Friendly: Low thermal conductivity significantly reduces heat loss, supporting enterprises in achieving low-carbon production.

Typical Application Scenarios

• Lining and backing of industrial kilns (long-term operating temperature: 1150°C–1300°C)

• Thermal insulation sealing for high-temperature pipelines, furnace doors, and expansion joints

• High-temperature insulation gaskets (≤1280°C)

• Base material for ceramic fiber modules/folded blocks

Currently, Long Keter's ceramic fiber product series have been exported to various regions worldwide and are widely applied in industries such as steel, cement, and ceramics. Adhering to the philosophy of "empowering insulation with technology and safeguarding safety with quality," we provide customers with end-to-end services ranging from materials to construction guidance.
