Borosilicate Glass Wiki

Borosilicate Glass Meaning

Borosilicate glass is a specialized glass type composed of silica (SiO₂) and boron trioxide (B₂O₃), typically containing 80% silica and 13% boron. This unique composition gives it exceptional properties that distinguish it from regular soda-lime glass:

• Thermal shock resistance (withstands ΔT up to 165°C)

• Low thermal expansion coefficient (3.3×10⁻⁶/K)

• High chemical durability (resists acids and alkalis)

• Optical clarity (similar to crystal glass)

  
  

First developed by Otto Schott in 1893, this glass revolutionized industries from laboratory equipment to premium drinkware like borosilicate glass wine glasses.

Borosilicate Glass Material

The material science behind borosilicate glass explains why leading borosilicate glass manufacturer prefers it:

Key Components of Borosilicate Glass

Physical Properties of Borosilicate Glass

• Density: 2.23 g/cm³

• Softening point: 820°C

• Refractive index: 1.47

• Dielectric strength: 20-25 kV/mm

  
  

These properties make it ideal for:

• Custom borosilicate glass laboratory apparatus

• Single wall glass cups for specialty coffee shops

• Luxury borosilicate glass decanters

Borosilicate Glass Function

The functional superiority of borosilicate glass makes it the preferred choice for borosilicate glassware suppliers:

1. Thermal Performance

• Withstands direct flame exposure (Bunsen burners)

• Safe for freezer-to-oven transitions (-30°C to 400°C)

• Used in glass coffee cup factory production

2. Chemical Resistance

• pH stability range: 0-14

• Non-porous surface prevents flavor absorption

• Meets USP Type I standards for pharmaceuticals

3. Mechanical Strength

• 2-3× more impact-resistant than standard glass

• Maintains clarity after 1,000+ dishwasher cycles

Borosilicate Glass Working

Top borosilicate glass manufacturers follow this precision process:

1. Batch Preparation

• High-purity silica sand (99.9% SiO₂)

• Anhydrous boron oxide (technical grade)

2. Melting

• 1600°C furnace temperatures

• Continuous stirring for homogeneity

• Special crucibles to prevent contamination

3. Forming Techniques

• Blowing: For borosilicate glass decanter and drinkware

• Pressing: For single wall glass cup and bakeware

• Tube Drawing: For laboratory glassware

4. Annealing

• Controlled cooling at 1-2°C/minute

• Stress relief at 560°C for 1 hour
