Quartz tube and electric wire tube are two common electric heating elements, they are different in material, structure and application:

1. Material:

  - Quartz tube: mainly made of high purity quartz (SiO2), with high heat resistance and good light transmission.

  - Electric heating wire tube: usually made of metal electric heating wire (such as nickel-chromium alloy, ferro-chromium aluminum alloy, etc.) and ceramic tube or other non-metallic materials.

2. Structure:

  - Quartz tube: is a hollow tubular structure, can be directly energized heating, can also be used as a carrier for other heating elements.

  - Electric heating wire tube: the internal contains one or more metal electric heating wire, the external is usually wrapped by ceramic and other materials to form a complete heating unit.

3. Heating principle:

  - Quartz tube: heat is generated by current passing directly through the wall of the quartz tube, which belongs to resistance heating.

  - Electric heating wire tube: the current through the built-in electric heating wire to generate heat, the heat is then conducted to the outside of the tube heating medium.

4. Temperature resistance:

  - Quartz tube: high temperature resistance, can withstand a wide range of temperatures, usually above 1000 ℃.

  - Electric wire tube: temperature resistance is relatively low, depending on the material of the electric wire and tube wrapping material.

5. Light transmittance:

  - Quartz tube: has good light transmission, suitable for applications that require observation of the heating process.

  - Electric heating wire tube: generally opaque, not applicable to the need to observe the internal process.

6. Application areas:

  - Quartz tube: commonly used in laboratory instruments, high-temperature furnaces, infrared heaters and so on.

  - Electric heating wire tube: widely used in household appliances, industrial heating equipment, drying equipment, etc.

When choosing a heating element, you should decide whether to use quartz tube or electric filament tubes according to the specific application requirements, heating temperature, environmental conditions and other factors.
