Features:
- High-borosilicate glass is a specialized glass distinguished by its high boron trioxide content (typically 12-15%). Its defining property is an extremely low coefficient of thermal expansion (≈3.3 × 10⁻⁶/K), granting exceptional resistance to thermal shock, allowing rapid temperature changes without cracking.
- Chemically, it is highly inert and durable, with superior resistance to hydrolytic, acids, salts, and halogens compared to ordinary soda-lime glass. It exhibits high mechanical strength, excellent electrical insulation, and good transparency across a wide optical spectrum.
- Key physical properties include a density of ~2.23 g/cm³, a softening point around 820°C, and high chemical stability (hydrolytic class 1). These attributes make it indispensable for laboratory ware, chemical apparatus, high-performance lighting, cookware, and precision optics.
Application recommendations:
- Long-term safe operating temperature: ≤450°C
- Short-term tolerance peak temperature: 500°C
- Softening point: 820°C
- Thermal shock temperature difference (∆T): Can withstand instantaneous temperature differences ranging from 150°C to 200°C.
- Effective light transmission spectral range: 350nm～2500nm
- Hydrolytic Resistance: Achieves the highest level (Grade 1, according to DIN ISO 719 standard). Practically insoluble in water and remains extremely stable even under high-temperature and high-pressure conditions
- Acid and salt resistance: It exhibits exceptional resistance to all inorganic and organic acids except hydrofluoric acid (HF) and hot phosphoric acid, as well as salt solutions.
- Alkali resistance: Although alkaline solutions are highly corrosive to all silicate glasses, borosilicate glass exhibits significantly superior alkali resistance compared to ordinary soda-lime glass, owing to its high silica, high boron, and low alkali composition.
- Resistance to halogens and solvents: It exhibits excellent stability against halogens such as chlorine and bromine, as well as most organic solvents.
