Alumina Granulation Powder

Name

Alumina Granulation Powder
Features

Alumina granulated powder is a granular powder prepared to adapt to the production process of alumina ceramics. It has characteristics such as high purity, high activity, low-temperature sintering, high density, non-sticking to molds, no cracking, no porosity in the sintered product, and good consistency of the powder.
Explanation

JFM's alumina granulation powder features a robust morphology, high purity, and good reactivity. It offers high green body strength, low sintering temperature, high ceramic density, and a uniform microstructure, making it suitable for the manufacturing of electronic substrates, structural ceramics, and insulating ceramics. With superior flowability and packing performance, JFM's alumina granulation powder is easy to compact and shape, resulting in high density and strength after sintering, making it an ideal material for high-end engineering ceramics.
