Quartz bell cover
Quartz bell jars, as the name suggests, refer to bell jars made of high-purity quartz glass.
Main features:
Material: Mainly made of quartz glass (fused quartz or synthetic quartz). Quartz glass has extremely high purity, very low impurity content, and excellent optical transparency.
Features:
High transparency: It has high light transmittance over a wide range of wavelengths (from ultraviolet to near-infrared), far exceeding that of ordinary glass.
High temperature resistance: Melting point up to 1700 ° C or more, can work stably in high temperature environments for a long time, with a very low coefficient of thermal expansion (about 1/10 to 1/20 of ordinary glass), good thermal stability, and is not prone to cracking due to sudden temperature changes.
Chemical stability: Excellent resistance to most acids, alkalis, and salt solutions, with strong corrosion resistance.
Mechanical strength: It has good mechanical strength and hardness.
Electrical insulation: It is an excellent insulator.
Structure: Usually cylindrical or square, with an opening or sealing structure at the top and a support or connection at the bottom. The overall shape is like an upside-down bell, hence the name "bell jar".
Due to its excellent comprehensive performance, quartz bell covers are often used as containers or isolation covers that require protection of the internal environment, observation of internal conditions, or special processing.
Application of quartz bell cover
Quartz bell covers are widely used in many high-tech fields due to their unique properties.
Semiconductor manufacturing: This is one of the most important application fields for quartz bell jars.
Epitaxial growth: In the production of silicon wafers or other semiconductor materials, the substrate needs to be placed in a quartz bell cover, and epitaxial growth is carried out under ultra-high vacuum or a specific atmosphere. The bell cover can effectively isolate external pollution and maintain the process environment.
Etching and deposition: In processes such as plasma etching or chemical vapor deposition (CVD), the quartz bell cover acts as a reaction chamber, capable of withstanding high temperatures and corrosive gases while ensuring the purity of the process environment.
Diffusion and oxidation: In semiconductor doping and oxidation processes, quartz bell covers provide a high-temperature, clean reaction space.
Optics and optoelectronics:
Laser: acts as a resonator or housing for some types of lasers, such as CO2 lasers, to protect optical components while allowing laser light to pass through.
Optical component protection: Protects sensitive optical components from dust, moisture, or chemical contamination.
Photodetector testing: When testing photodetectors, it is used as a camera obscura or a container that provides a specific light environment.
Scientific research and laboratories:
Vacuum systems are used to create vacuum or inert gas environments for physical and chemical experiments, such as material characterization, spectroscopic analysis, and so on.
High temperature experiment: as a reaction vessel or observation window with high temperature resistance.
Sample protection: Protect environmentally sensitive samples from exposure to air or contamination.
Vacuum technology: as a cavity or key component of vacuum equipment (e.g. vacuum coating machine, vacuum furnace), taking advantage of its high temperature resistance and low outgassing rate (under high vacuum).
Medical equipment: It may be used in some medical equipment that requires high temperature sterilization or special environmental treatment.
Special lighting: a tube that protects high-intensity discharge lamps (such as UV lamps) while allowing specific wavelengths of light to pass through.
Customized service for quartz bell covers
Due to the different requirements for the size, shape, thickness, transparency, temperature resistance level, and interface mode of quartz bell covers in different application scenarios, the customization service of quartz bell covers is very important and common. Customized services usually include the following aspects:
Size and shape customization:
Diameter/side length: Customize the caliber of the bell jar according to the internal space or process requirements of the equipment.
Height: Adjust the vertical size of the bell jar.
Special shapes: In addition to standard cylinders or square columns, special shapes such as cones and special shapes can be customized according to requirements.
Wall Thickness Customization: Adjust the wall thickness of the quartz bell cover according to the requirements of pressure resistance, temperature resistance, mechanical strength, etc. Thicker walls provide better mechanical strength and thermal stability, but will sacrifice some transparency.
Interface and flange customization:
Interface position: A specific interface hole is opened on the side or bottom of the bell jar.
Flange design: According to equipment connection standards (such as CF, K, VF and other vacuum flange standards, or non-standard flanges), custom flange size, sealing surface form (flat, concave, convex) and connection thread/bolt hole.
Window and viewing hole customization: Machining a window or viewing hole of a specific size and shape on a bell jar for mounting sight glasses or directly observing the interior.
Special treatment:
Polishing: High-precision polishing of the inner and outer surfaces to improve transparency and finish.
Etching/Marking: Etching of scales, text, or patterns on the surface of the bell jar.
Coating: Coating the surface with anti-reflection film, reflective film or other functional film as required.
Bending: The quartz tube is bent into a specific arc and then sealed into a bell jar.
Material selection: According to the operating temperature, chemical environment, etc., choose different types of quartz glass, such as high-purity quartz, synthetic quartz, etc.
The quartz bell cover is a high-performance specialty glass component that plays a key role in the high-tech industry. Its wide application field and high degree of customizability enable it to meet a wide range of demanding process and environmental requirements.
