Basalt Fiber
What is Basalt Fiber?
Basalt fiber is a high-performance material made from volcanic rock, specifically basalt. It is produced by melting crushed basalt rock at high temperatures (around 1,400-1,600°C) and then extruding it through fine nozzles to form continuous filaments. These filaments are gathered into strands and can be processed into various forms such as rovings, fabrics, mats, or chopped fibers. Basalt fiber is known for its excellent mechanical properties, chemical resistance, and thermal stability, making it a popular alternative to materials like fiberglass, carbon fiber, or steel in many applications.
Key Properties and Advantages
- High tensile strength: Superior to many synthetic fibers, offering durability.
- Excellent thermal resistance: Can withstand temperatures up to 700°C.
- Chemical resistance: Performs well in acidic and alkaline environments.
- Low moisture absorption: Maintains properties in humid conditions.
- Eco-friendly: Made from natural, abundant basalt rock with minimal processing.
- Lightweight: Reduces overall weight in composite applications.
- Good electrical insulation: Suitable for electrical applications.

Frequently Asked Questions (FAQ)
What is basalt fiber made from?
Basalt fiber is made from natural basalt rock, which is melted and extruded into fine filaments. The process involves crushing the rock, melting it at high temperatures, and drawing it through bushings to form continuous fibers.
How does basalt fiber compare to fiberglass?
Basalt fiber offers higher tensile strength, better thermal resistance, and superior chemical stability compared to fiberglass. It is also more environmentally friendly as it uses natural raw materials without additional chemicals.
Is basalt fiber environmentally sustainable?
Yes, basalt fiber is considered eco-friendly because it is derived from abundant volcanic rock, requires less energy to produce than synthetic fibers, and generates minimal waste. It is also recyclable and non-toxic.
What are the main applications of basalt fiber?
Basalt fiber is widely used in construction for reinforcing concrete, in automotive parts for weight reduction, in marine applications for corrosion resistance, and in aerospace for high-performance composites, among others.
Can basalt fiber be used in high-temperature environments?
Absolutely. Basalt fiber can withstand temperatures up to 700°C, making it suitable for applications such as fireproof materials, industrial insulation, and exhaust systems.
How is basalt fiber processed into products?
After extrusion, basalt filaments are collected into rovings, which can be woven into fabrics, chopped into strands, or needled into mats. These forms are then used in various manufacturing processes like pultrusion or molding.
Does basalt fiber corrode or degrade over time?
No, basalt fiber is highly resistant to corrosion, UV radiation, and chemical exposure, ensuring long-term durability without significant degradation in most environments.
What is the cost of basalt fiber compared to other materials?
Basalt fiber is generally more expensive than fiberglass but cheaper than carbon fiber. Its cost-effectiveness comes from its durability and performance benefits, reducing long-term maintenance and replacement costs.
Is basalt fiber safe for handling and use?
Yes, basalt fiber is non-toxic and does not release harmful particles during handling. However, standard safety precautions for fibrous materials, such as wearing gloves and masks, are recommended during processing.
