Payment Details
1. Soda-lime Glass (Ordinary Flat Glass)
- Composition: Mainly composed of silicon dioxide (SiO₂, approximately 70%), sodium oxide (Na₂O), and calcium oxide (CaO).
- Characteristics: Easy to produce, low cost, but poor thermal stability and brittle.
- Applications: The most common type of glass, used for doors, windows, bottles, jars, and everyday utensils.
2. Borosilicate Glass (Heat-Resistant Glass)
- Composition: Based on soda-lime glass, boron oxide (B₂O₃) is added.
- Characteristics: Low coefficient of thermal expansion, high temperature resistance, resistance to rapid temperature changes (not easily cracked by sudden heating and cooling), good chemical stability.
- Applications: Laboratory instruments (such as beakers and test tubes), heat-resistant tableware (such as baking pans and glass pots), high-end flashlight lenses, etc. Well-known brands include Pyrex.
3. Aluminosilicate Glass
- Composition: Contains a large amount of aluminum oxide (Al₂O₃) and silicon dioxide (SiO₂).
- Characteristics: High hardness, scratch resistance, high mechanical strength, superior performance compared to borosilicate glass.
- Applications: Cover glass for high-end mobile phones/tablets, aviation glass, etc. Well-known brands include Corning Gorilla Glass.
4. Quartz Glass
- Composition: Silicon dioxide (SiO₂) content is above 99%.
- Characteristics: Excellent heat resistance (softening point up to 1700℃), wide light transmission spectrum (from ultraviolet to infrared), high purity, and excellent chemical stability. However, it is expensive.
- Applications: Semiconductor industry, optical devices, observation windows in high-temperature furnaces, ultraviolet lamps, etc.
