Quartz Bell Jar
Semicorex Quartz Bell Jar stands out as a critical component of quartz glass tube by providing comprehensive benefits in challenging environments.
Unmatched High-Temperature Resistance of Fused Silica SiO2
One of the standout attributes of the Quartz Bell Jar is its remarkable resistance to high temperatures. The softening point of fused silica sio2 reaches approximately 1730°C, allowing it to maintain integrity and functionality even under prolonged exposure to high temperatures. For continuous use, the fused silica sio2 comfortably withstands temperatures up to 1100°C. In scenarios requiring short-term exposure, it can endure temperatures as high as 1450°C without compromising its structural integrity.
Superior Corrosion Resistance
Engineered through a specialized manufacturing process that removes up to 90% of naturally-occurring alkalis, our Quartz Bell Jars exhibit extraordinary corrosion resistance. This distinctive feature of fused silica sio2 ensures that the material remains unaffected by harsh chemical environments, outperforming other engineering materials. Specifically, the acid resistance of the fused silica sio2 is 30 times greater than that of ceramics and 150 times that of stainless steel. This remarkable chemical stability is especially pronounced at elevated temperatures, making our Quartz Bell Jar the material of choice for applications in aggressive chemical environments, such as semiconductor processing.
Outstanding Light Transmission Properties
Our Quartz Bell Jars boast excellent light transmission across a broad spectrum of wavelengths. The fused silica sio2 offers exceptional transmittance in the ultraviolet (UV) to infrared (IR) spectral bands. Specifically, the visible light transmittance exceeds 93%. In the ultraviolet spectral region, the maximum transmission rate surpasses 80%, providing superior performance in UV-sensitive applications such as photolithography and UV curing.
Excellent Electrical Insulation Properties
Fused silica sio2 is renowned for its superior electrical insulation properties, and our Quartz Bell Jars are no exception. The resistance value of fused silica sio2 is approximately ten thousand times greater than that of ordinary quartz, making it an excellent electrical insulator. Even at high temperatures, our Quartz Bell Jars maintain their electrical insulating properties, ensuring safe and reliable performance in electrically demanding environments.
Superior High-Vacuum Characteristics
In addition to its other remarkable properties, our Quartz Bell Jars also feature excellent high-vacuum characteristics. The fused silica sio2’ s inherent purity and structural integrity ensure that it can maintain a high vacuum without outgassing or degradation. This makes our Quartz Bell Jars particularly suitable for applications in high-vacuum environments, such as vacuum coating, electron microscopy, and space simulation chambers.
Customizable Dimensions for the Quartz Bell Jar
Understanding that each application has unique requirements, we offer our Quartz Bell Jars in various diameters and lengths. This flexibility allows you to select the dimensions that best fit your specific needs, ensuring optimal performance and compatibility with your existing equipment.
