There are some significant differences between quartz glass rods and ordinary glass rods in terms of composition, properties and applications:

1. Compositional differences:

  - Quartz glass rods: the main component is high-purity silicon dioxide (SiO2), usually containing more than 99% SiO2.

  - Ordinary glass rods: the main component is also silicon dioxide, but usually add other components such as sodium, calcium, magnesium and other oxides to lower the melting point and improve processing performance.

2. Heat resistance:

  - Quartz glass rods: high heat resistance, can be used at temperatures up to about 1000 ° C without softening.

  - Ordinary glass rods: lower heat resistance, usually can only be used at a temperature of not more than 300 ° C or so.

3. Chemical stability:

  - Quartz glass rods: good resistance to most chemical reagents, will not react with them, suitable for strong acids, alkalis and other corrosive media experiments.

  - Ordinary glass rods: less chemically stable, easily eroded by strong acids and alkalis, especially at high temperatures.

4. Light transmittance:

  - Quartz glass rods: good light transmission, especially in the ultraviolet region, suitable for experimental operations requiring high light transmission.

  - Ordinary glass rods: poor light transmission, especially in the ultraviolet and infrared region.

5. Melting point:

  - Quartz glass rods: high melting point, about 1700 ° C or so.

  - Ordinary glass rods: lower melting point, usually between 600°C and 800°C.

6. Areas of application:

  - Quartz glass rods: due to its superior performance, commonly used in high-temperature experiments, precision analysis, semiconductor manufacturing and other fields.

  - Ordinary glass rods: suitable for general laboratory operations, such as stirring, simple filtration, etc., lower cost, suitable for large-scale use.

Quartz glass rods are superior to ordinary glass rods in terms of high temperature resistance, chemical stability and light transmittance, but the cost is also relatively high, so the choice needs to be based on the specific requirements of the experiment and budget.
