    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...
