GB/T 26824-2020 "Nano Alumina" specifies the technical requirements, testing methods, and quality evaluation system for nano alumina, and is applicable to the quality inspection and acceptance of related products. The standard introduces new testing items such as the pH value of suspensions and microscopic morphology. Testing requires the use of instruments such as pH meters, transmission electron microscopes (TEM) or scanning electron microscopes (SEM), along with laser particle size analyzers. By measuring key indicators such as particle size distribution, purity, and microstructure, the standard ensures the stable performance of nano alumina products and provides a quality basis for their application in fields such as materials and chemical engineering.
