3. Quartz Wool Detailed Description & Manufacturing Process

Quartz wool is a high-purity fibrous material formed by the random asymmetric arrangement of fragile and flexible fused quartz fibers, with a cotton-like fluffy appearance. It is manufactured from high-quality natural quartz crystals and ultra-high-purity SiO₂, sharing consistent core properties with fused quartz products.

The standard manufacturing process of the SR-Qwool series quartz wool: high-purity quartz rods (with 10-20ppm metallic impurities) are extruded into micron-diameter fibers, which are then collected, processed, and packaged into final products. Our silica wool is completely free of binders, odors and volatile substances, with no additional harmful additives.

4. SR-Series Quartz Wool Fiber Grade Classification

The SR-Qwool series quartz wool is classified into multiple grades by fiber monofilament diameter to meet diverse application requirements, with detailed specifications as follows:

4.1 SR-Qwool-UF (Ultra-Fine Grade Quartz Wool)

• Fiber Diameter: ~3μm (1-3μm for precision grade)
• Core Features: High surface area, ultra-thin fiber thickness, relatively high pricing
• Intended Use: Gas chromatography quartz wool, precision instrument filling

4.2 SR-Qwool-F (Fine Grade Quartz Wool)

• Fiber Diameter: 3-9μm (sub-divided into 3-5μm, 4-8μm, 7-9μm sub-grades)
• Core Features: Balanced surface area and processability
• Intended Use: Elemental analysis, catalyst support, laboratory analytical instrument filling

4.3 SR-Qwool-C (Coarse Grade Quartz Wool)

• Fiber Diameter: 8-15μm (12-15μm for standard coarse grade)
• Core Features: High structural strength, excellent high-temperature resistance
• Intended Use: High-temperature tube furnaces, industrial catalyst support, large-scale instrument filling

5. Quartz Wool Key Properties & Core Advantages

5.1 Key Core Properties of Quartz Wool

• Thermal Performance: Outstanding high-temperature resistance, non-flammable, non-combustible, low thermal conductivity, excellent thermal stability at both low and high temperatures, with a softening point up to 1730 ºC.
• Chemical Performance: Excellent chemical inertness, resistant to strong acids and strong bases (except hydrofluoric acid HF and hot phosphoric acid), insoluble in water and organic solvents, with no chemical reaction with most corrosive media.
• Electrical Performance: Low dielectric constant, superior high-temperature electrical insulation performance, better than high-silica fibers.
• Physical Performance: Low thermal mass, high purity, low outgassing, good flexibility and processability, with a stable fluffy cotton-like structure.

5.2 Core Advantages of SR-Qwool Series Quartz Wool

• Maximizes the surface area available for sample vaporization
• Enables homogeneous and rapid sample vaporization
• Effectively prevents boiling point discrimination during analytical tests
• Protects chromatographic columns and analytical instruments from non-volatile contaminants
• Maintains stable performance in harsh high-temperature and corrosive working environments

6. Quartz Wool Main Application Fields

The SR-Qwool series quartz wool is widely used in laboratory scientific research, industrial manufacturing, semiconductor, optics, environmental protection and other fields, with core applications including:

6.1 Thermal Insulation

• As high-temperature insulation material for furnace linings, kilns, industrial heaters and high-temperature reaction devices
• Used as an IR heat diffuser, with excellent thermal insulation effect under extreme high-temperature conditions

6.2 Filtration

• Used as a filter medium for high-temperature gas and corrosive fluid filtration
• Applied in air pollution control, strong acid filtration, and fine particulate matter removal from gas/liquid streams

6.3 Analytical Chemistry & Sample Preparation

• Used as filler for analytical instruments, support bed in distillation and HPLC columns
• Applied in sample preparation for gas chromatography, mass spectrometry and other analytical scenarios, to trap and separate samples based on physical and chemical properties
• Used for fixation of packing materials in analytical equipment
• Special pretreatment guidance: Pesticides and other easily degradable samples are treated with silane, while acidic samples including fatty acids and sulfur compounds are treated with phosphate.

6.4 Catalysis

• Used as support material for catalysts in chemical reactions
• As an insulation bed for catalysts in reactor columns; its high surface area structure provides excellent loading performance for catalysts

6.5 Electrochemistry

• Used as support material for electrodes in electrochemical applications
• Ideal for use in electrolytic cells due to its ultra-high purity and low reactivity

6.6 Other Applications

• Filler for various precision instruments
• Optical industry auxiliary materials
• Semiconductor manufacturing process auxiliary materials
• Other industrial and laboratory R&D scenarios
