Powder Si3N4 Description
ZhenAn's ceramic-grade silicon nitride powder offers a number of advantages, including a high alpha phase content, high powder purity, a narrow grain size distribution, and high sintering activity.
The powder is of high purity with a very low impurity content, typically below 200ppm. It is highly dispersible, with a uniform and reasonable particle size distribution, and demonstrates stable performance. It contains a high proportion of the α phase and exhibits excellent sintering activity. It is therefore well suited to products that require high sintering performance, such as silicon nitride cutting tools and bearing balls.
