1. Characteristics and advantages ofUltra-wear-resistant silicon nitride beads product materials

•  Ultra-Wear-Resistant Silicon Nitride Microbeads reduces media consumption and mill contamination in ultra-fine dispersion where product purity and fineness are critical thanks to its very low wear rate.

A. Ultra-fine Grain Size: Higher fineness of raw materials, lower wear rate, longer service life.

B. Ultra-high Density: Ultra-dense inner structure, strong impact resistance, no broken beads during use.

C. Uniform Bead Size Distribution: More stable grinding, results more sustainable productions.

D. Smooth Surface: Lower self-wear rate.

2. Production technology of silicon nitride beads

• By using the original extrusion molding process, and the bead is uniform and dense;

• By using Vacuum sintering process, and the density is greater than 3.2g/cm³;

• Super wear-resistant, more than 10 times more wear-resistant than zirconia beads, nearly 20 times more wearresistant than high-purity zirconia beads, highly cost-effective;

• Higher actual linear velocity, effectively improve the efficiency of ultra-fine dispersion by more than 30%;

• The density is only 53% of zirconia beads, which can reduce energy consumption and heat generation in the ultrafine process.

3. Applications 

• Silicon Nitrde beads（Φ0.1-2.0）suitable for ultrafine dispersion of high-end materials, especially for working conditions with high requirements for product purity and fineness.
