Lanthanum Hexaboride Ceramic Part, LaB6 Parts
Lanthanum hexaboride (LaB6) ceramic parts are high-performance components used in various applications, including electron microscopy and vacuum technology. These parts are made of a high-purity LaB6 powder that is molded and sintered under high temperatures and pressures to create a dense and durable ceramic structure.
LaB6 ceramic parts are known for their excellent thermal and electrical conductivity, low outgassing rates, and high-temperature stability. They are resistant to oxidation and can withstand harsh vacuum environments, making them ideal for use in high-temperature furnaces, semiconductor processing, and other demanding applications.
Common LaB6 ceramic parts include crucibles, plates, rings, and other custom-machined components. They are available in a range of sizes and shapes to meet specific application requirements. The high purity of LaB6 powder used to make these parts ensures high-quality and consistent performance in critical applications.
