Introduction to the characteristics of quartz glass

In the market for smoking products , more and more products use quartz glass as a raw material,such as Quartz Banger, Glass bowls and so on. So what is a quartz glass? What are the characteristics of quartz glass? Let’s get about it.

What’s  the quartz glass?

Quartz glass is a type of glass made from silica, known for its high purity and excellent thermal stability. It has excellent chemical resistance and is transparent to ultraviolet light, making it ideal for applications in optics and electronics. Quartz glass also exhibits low thermal expansion, which helps maintain dimensional stability under temperature changes. Its high melting point and durability make it suitable for high-temperature applications.

What are the characteristics of quartz glass?

1.Physical Properties

High Purity: SiO₂ content ≥99.95%, extremely low impurities.

Low Thermal Expansion Coefficient: ≈5.5×10⁻⁷/°C (from room temperature to 1000°C).

High Transparency: Excellent transmission from UV (170 nm) to IR (3500 nm).

Low Density: ≈2.2 g/cm³.

2.Chemical Properties

Corrosion Resistance: Soluble only in hydrofluoric acid (HF) and hot phosphoric acid.

Hydrolytic Resistance: Stable under high temperature and humidity.

3.Mechanical Properties

High Hardness: Mohs hardness ≈7.

High Brittleness: Prone to fracture; requires careful handling.

4.Thermal Properties

High-Temperature Resistance: Long-term service temperature up to 1000°C.

Low Thermal Conductivity: ≈1.4 W/(m·K).

Advantages & Disadvantages

Advantages: High-temperature resistance, broad transparency, chemical inertness.

Disadvantages: High processing cost, brittleness.

Based on the above characteristics, quartz glass products are a good choice for Smoking consumers.
