Product Description
Product Description:
95% zirconium silicate beads are essential in the production of ceramic substrates used in power electronics, LED packaging, RF/microwave devices, and semiconductor modules. Common substrate materials include alumina (Al₂O₃, 96% and 99.5%), aluminum nitride (AlN), silicon nitride (Si₃N₄), and beryllium oxide (BeO)—all of which require ultra-fine, high-purity powders and precise surface finishing to meet the stringent demands of electronic packaging.
Features
-
Ultra-fine particle size control: Substrate-grade ceramic powders require D50 of 0.3–0.8 μm to achieve high sintered density (>99% theoretical density) and fine grain structure. The high density (~6.0 g/cm³) and hardness (Vickers ~1200) of 95% ZrO₂ beads deliver the energy needed to reach these specifications efficiently.
-
Thermal conductivity preservation: For AlN substrates used in high-power electronics, thermal conductivity (>170 W/m·K) is the key performance metric. Any impurity introduced during grinding—especially oxygen, silicon, or transition metals—can form scattering phases at grain boundaries, drastically reducing thermal conductivity. The chemical inertness and ppm-level wear rate of 95% ZrO₂ beads minimize such contamination.
-
Narrow particle size distribution: Uniform particle size directly impacts:
- Sintering temperature: Narrow distribution allows lower sintering temperatures, reducing energy costs
- Grain size uniformity: Fine, uniform grains improve mechanical strength and thermal shock resistance
- Flatness after co-firing: Uniform shrinkage during sintering maintains substrate flatness, critical for subsequent metallization
-
Dielectric property stability: For RF/microwave substrates, dielectric constant and loss tangent must be tightly controlled. Impurity contamination from grinding media can create localized dielectric anomalies. 95% ZrO₂ beads prevent this through their chemical stability and minimal wear debris.
