Product Details
High-Strength Silicon Nitride Microbeads
• High-Strength Silicon Nitride Microbeads is produced by extrusion moulding and low-temperature sintering, giving a dense, mirror-smooth bead for ultra-fine dispersion where product purity and fineness are critical.
• The beads are chemically inert and non-contaminating, so the purity of the milled material is preserved and batch-to-batch consistency stays stable over a long service life.
• Available in a range of sizes and to customer drawings; batch quantities and tooling can be arranged on request.
1. Characteristics and advantages ofUltra-wear-resistant silicon nitride beads product materials
• High-Strength Silicon Nitride Microbeads is produced by extrusion moulding and low-temperature sintering, giving a dense, mirror-smooth bead for ultra-fine dispersion where product purity and fineness are critical.
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.
