Electron gun and ion source assemblies work in harsh conditions—high voltage, high temperatures, and ultra-high vacuum alike. This is especially true for ion repeller insulators, a key interface component where reliable electrical isolation and airtight vacuum sealing are both must-haves.   Our glazed alumina ceramic tubes with precision internal threading—engineered as Ion Repeller Ceramic Tubes—are made specifically for these tough applications. As the core insulating part of repeller insulator assemblies, they pair perfectly with alumina bolts, delivering steady performance while ensuring firm mechanical fastening and reliable electrical isolation.     High-Vacuum Design: A Core Engineering Challenge Keeping long-term vacuum integrity in high-voltage setups is a classic engineering hurdle. Insulators have to do three jobs at once: act as mechanical support, block electrical current, and seal the vacuum—all while staying stable when hit with thermal and electrical stres...

In semiconductor equipment, industrial control systems, and high-reliability electronic systems, the package not only provides electrical connections but also directly affects the long-term stability of the device in high-temperature, vacuum, or otherwise demanding environments. Although traditional plastic-encapsulated SOP packaging is cost-effective and fast to produce, it is susceptible to aging, leakage, or performance degradation under high humidity, high temperature, and long-term operation conditions. In contrast, ceramic packaging has inherent advantages in terms of air tightness, material stability, and service life. Among them,  Ceramic Small Outline Package (CSOP)  is a type of ceramic package that combines mature manufacturing techniques with surface mount requirements. It integrates the high stability of ceramic materials with the compact form factor of SOP (Surface Mount Package), and is widely used in electronic systems that have high requirements for reliabilit...

Alumina ceramic  is widely applied in the high-temperature industry because of its excellent resistance to high temperatures. It can withstand high temperatures up to 1800℃, in addition to its stable chemical properties, high mechanical strength, and electrical insulation. So  Alumina ceramic tube  is commonly used in high-temperature furnaces, thermocouples tubes, insulating tubes, and corona electrode’s square ceramic tubes. In this articles, we would like to discuss how to use alumina ceramic tubes at high temperatures to ensure optimal performance and longevity.

One Primary Use:Water-cooled crucible liner,Application as Crucible Liner for copper crucible,This high-purity alumina component is specifically engineered as a thermal insulation liner for water-cooled crucible systems in molten aluminum operations.
