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.

Innovacera’s metallised ceramic rings are used in image intensifier tubes for night vision equipment and other instruments. Specifications: -High purity alumina ceramics-95-96% alumina. -Metallization-Mo/Mn metallized with Nickel plating. -Customised sizes and metallisation patterns available. Features: Shape As per request. Mostly are using ring shape Size Big ring OD30.5*ID24.2*3.20mm Small ring OD30.5*ID27.5*1.06mm Or custom by your drawing Color White Properties l Ultra-high vacuum compatibility (10 -8  to 10 -9  mbar.l/s) l Good dielectric strength (13KV/mm in AC and 42KV/mm in DC) Four ceramic rings are using in one image intensifier tubes. Each metalized ceramic ring serves not only as a part of the electrode conductive path, but also as a mechanical positioning and vacuum holding function. The rings are often precisely bonded through brazing or metal support structures to form a cylindrical main structure. Functional: Realize electrode cascade and electric fi...

  Innovacera Silicon Nitride Grinding Media Balls were made by 3 forming ways: titration, roll, and CIP (cold isostatic pressing ) forming and they were gas pressing sinetering in 1800～2100℃. The purity of silicon nitride is 99% and generally, if the diameter size is more than 3mm, we will choose the CIP forming way. Silicon nitride grinding balls possess excellent features, including chemical inertness, low friction and heat generation, electrical insulation, non-magnetism, high strength, and corrosion resistance. Compared with other grinding media, the  silicon nitride (Si₃N₄)  milling media balls improve energy efficiency, reduce mechanical wear and ultra-fine grinding and dispersion. It is an ideal grinding media when high wear resistance, minimal contamination and less abrasion is required, such as semiconductor slurries, pharmaceutical dispersions, and battery material milling. Our silicon nitride media balls main size is 0.2 mm – 20 mm. Si3N4 Milling Ball General ...

    The causes of color difference in AlN ceramics are related to raw material preparation, processing technology (sintering temperature fluctuation, protective atmosphere), microstructure, and environmental factors. The following provides a comprehensive analysis based on related research:   1. Surface Color Change Due to Oxidation Behavior AlN ceramics easily react with oxygen at high temperatures to form aluminum oxide (Al₂O₃). The thickness and structure of the oxide layer significantly affect the surface color.   Oxidation kinetics: Differential thermal analysis shows that the mass change of AlN during variable temperature oxidation is related to the degree of oxidation. Different stages of the oxidation reaction may be accompanied by gradual changes in color.   2. Influence of Preparation Process and Raw Material Purity Difference in synthesis methods: The hydrothermal–carbothermal synthesis method can reduce impurity introduction by regulating precursor h...

  Innovacera has rich experience in producing zirconia   ceramic plungers   for the diesel injector valve market and a highly precise ceramic machining process. The diesel injector valve is one of the main components of fuel diesel engine. The ceramic plunger's core material, Innovacera, is   zirconium oxide (ZrO2) ,   which is a good material of choice for joining ceramic and steel. Due to the material of the plunger is zirconia yttria fine grain, which has high corrosion resistance, and zirconia ceramic metering plungers can be machined with high precision, such as +/-0.005mm and good surface finish, which helps to improve the efficiency and stability of the diesel fuel injector.     Innovacera zirconia ceramic plungers with barrels were installed in diesel injector valves and widely used in QSM11 and ISM11diesel engine fuel injectors. In the diesel engines part, generally, this diesel injector ceramic core common model is 3411711, so if you need thi...
