Product Details
Ultra-wear-resistant Silicon Nitrde Microbeads
1. Brief introduction
Super wear resistance, wear resistance is more than 10 times that of zirconia beads, excellent cost performance.
2. Characteristics and advantages ofUltra-wear-resistant silicon nitride microbeads product materials
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.
3. Product process
• 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.
4. Applications
• Suitable for ultrafine dispersion of high-end materials, especially for working conditions with high requirements for product purity and fineness.
