Silicon Nitride Grinding Media Balls

By -

  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 ...

Analysis of the Causes of Chromatic Aberration in AlN Substrate Ceramics

By -
Image
    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...

Zirconia ceramic plunger for fuel diesel engines

By -
Image
  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...

The Application of BN Ceramic Nozzle

By -
Image
  BN is a hot-pressed hexagonal boron nitride with a unique combination of chemical, electrical, mechanical and thermal properties. It is suitable for a range of applications where high performance is required. The BN ceramic nozzle is used in various high-temperature and high-performance industries like aerospace and semiconductor, which has won much attention in recent years due to its unique properties below:     1. Exceptional Thermal Stability With a melting point of approximately 2900 ° C, the BN ceramic nozzle can be used for temperatures of 1800 °C and 2100 °C separately in high vacuum and an inactive gas environment. 2. Thermal Shock Resistance BN nozzles can withstand rapid temperature changes without cracking. So it can be used in places where temperatures can fluctuate dramatically. 3 . Extreme Corrosion Resistance Bo...
