Zirconia-containing ceramic fiber bulk is a high-end insulation and refractory bulk material capable of withstanding temperatures up to 1430°C. As part of the aluminum silicate fiber system, it represents a modern lightweight refractory material widely recognized in the industrial sector.
This product is manufactured from high-quality raw materials such as zircon sand and kaolin through advanced processes including high-temperature melting and fiberization. It combines the dual advantages of lightweight properties and high-temperature resistance, with core performance far surpassing that of traditional insulation materials:
Lightweight density: Significantly reduces the load-bearing requirements of equipment.
Excellent high-temperature resistance: Can stably withstand long-term operation above 1200°C, with a maximum temperature tolerance of 1430°C.
Superior thermal stability: Resists powdering and cracking under repeated thermal cycling.
Low thermal conductivity and small heat capacity: Effectively blocks heat transfer, reduces energy loss, and enhances equipment efficiency.
Strong resistance to mechanical vibration: Suitable for vibration-prone environments in industries such as metallurgy and power generation.
Minimal thermal expansion: Maintains dimensional stability at high temperatures, preventing seal failure due to expansion.
Outstanding thermal and acoustic insulation: Functions as both an efficient thermal barrier and an excellent sound-absorbing material, with an absorption rate exceeding 80% for mid-to-high-frequency sound waves above 500Hz.
As a foundational raw material, zirconia-containing ceramic fiber bulk can be further processed into various shaped products such as aluminum silicate fiber boards, felts, ropes, and blankets to meet installation requirements across diverse applications. Additionally, it serves as an environmentally friendly alternative to traditional asbestos materials, offering advantages such as high-temperature resistance, low thermal conductivity, lightweight density, extended service life, high tensile strength, excellent elasticity, and non-toxicity. This eliminates the health hazards associated with asbestos and aligns with the trend toward green and sustainable industrial development.
Core Performance Features:
Exceptional thermal insulation: Extremely low thermal conductivity creates an effective heat barrier in high-temperature environments, significantly reducing heat loss and improving energy utilization.
Excellent chemical stability: Highly resistant to acid and alkali corrosion, capable of withstanding harsh environments such as metallurgical flue gas and chemical media without degradation, thereby extending material lifespan.
Multiple additional functionalities:
Provides excellent electrical insulation for thermal and electrical insulation in electrical equipment.
Offers notable sound absorption and noise reduction, with over 80% absorption for mid-to-high-frequency sound waves above 500Hz, effectively reducing operational noise in industrial equipment.
Broad temperature adaptability: Suitable for continuous use above 1200°C, with a maximum tolerance of 1430°C, making it ideal for demanding applications such as metallurgical furnaces, power plant boilers, and chemical reactors.
This product is widely used in thermal equipment across industries including metallurgy, power generation, machinery, and chemical processing. It is applied for insulation in areas such as industrial kilns, high-temperature pipelines, boiler furnaces, and reactor interlayers, making it the preferred refractory material for achieving energy savings, emission reduction, and safe, stable equipment operation.
