  Magnesium-zirconium ceramic parts, the main components of tundishes in the steel and metallurgical industry The tundish is mainly used in the steel metallurgical process as a key component of the continuous casting process. Its primary function is to store and distribute molten steel, ensuring a continuous and stable flow from the ladle to the mold.   Main Components of a Tundish Tundish Body — The main structure that holds molten steel, typically consisting of a refractory lining and a steel shell.   Lining — Includes the working layer in direct contact with molten steel and the permanent layer for thermal insulation. Commonly made from refractory bricks, castables, or spray coatings.   Stopper Rod — A critical part for controlling the molten steel flow rate and regulating the steel level in the crystallizer.     Submerged Entry Nozzle (SEN) — Introduces molten steel into the crystallizer while preventing oxidation and splashing.   Sliding Gate Syst...

  What is Boron Nitride? Hexagonal boron nitride (h-BN) ceramic has a microstructure similar to graphite. It is manufactured by hot pressing boron nitride powders at temperatures up to 2000  ° C and high pressure. The maximum blank size is 500 × 500 × 200 mm, and it can be further machined into complex shapes.   Why Can Boron Nitride Ceramics Be Used in Ion Implanters? Ion implantation is a key process in semiconductor manufacturing, where wafers are doped with foreign atoms to modify material properties such as conductivity and crystal structure.     The high-current extraction electrode is the core of an ion implanter system. It must withstand temperatures up to 1400  ° C, strong electromagnetic fields, aggressive process gases, and high mechanical forces.   Therefore, components made from boron nitride insulator ceramics help ensure that this process remains efficient, precise, and free of impurities.   The unique combination of exceptional the...

  Metallized ceramic rings play a crucial role in image intensifier tubes used in night vision devices. Traditional image intensifier tubes typically utilize ordinary glass or a single metal component, resulting in drawbacks such as fragility, poor sealing, and insufficient thermal stability. Innovacera’s recently launched metallized ceramic rings for image intensifier tubes has solved these issues through ceramic-to-metal brazing technology.   The metallized ceramic rings in image intensifier tubes generally use high-purity alumina ceramics as substrates, which applied Mo/Mn metallization and nickel plating. Combined ultra-high vacuum compatibility and excellent dielectric strength.     These rings are not only acting as part of the electrode’s conductive path but also as elements for mechanical alignment, vacuum sealing, and structural support, thereby ensuring stable image intensifier operation even under extreme conditions. Typically, four rings are incorporated ...

Ceramic packaging  is the “case” that uses ceramic materials (like alumina, aluminum nitride, or beryllium oxide) as the housing or substrate for integrated circuits. It’s a protective enclosure or base that prevents the semiconductor chip from environmental damage and provides electrical connections to the outside world.
