Custom particle size distributions can be prepared according to specific process requirements.
High mechanical toughness and surface stability enable the production of high-strength ceramic bodies and wear-resistant building tiles. High resistance and heat dissipation are mandatory and can be used as insulation substrates for electronic devices and substrate layers. It is also very suitable for producing high hardness structural components, pump seals, valve seats, and ceramic liners. Serve as reactive micro powder filler in unformed single pieces and sintered bricks to improve fire resistance, thermal strength, and volume stability. And it can be used as a sharp grinding medium in polishing compounds and surface polishing pastes for precision metals, optical glass, and stone.
Our advanced deep processing equipment can precisely control the crystal morphology, prevent clumping, and promote uniform dispersion of adhesives. In addition to the standard 4-5 μ m grade, we also offer customized grinding and classification to achieve precise target particle sizes for dry pressing, casting, or extrusion. Factory direct manufacturing ensures complete batch traceability of container shipping, factory direct cost structure, and stable supply scheduling.
HUAO tailors particle size distributions and surface properties to match exact customer manufacturing techniques. Export packaging configurations include 25kg multi-ply bags and 1000kg/1200kg heavy-duty bulk sacks with polyethylene moisture barriers, fully palletized and shrink-wrapped for international logistics.
A1: Yes, HUAO operates in full compliance with certified ISO 9001, ISO 14001, and ISO 45001 management systems, conducting strict batch-wise testing on chemical purity, particle sizing, and alpha-phase content.
A2: HA-2 provides higher purity (Al₂O₃ ≥ 99.6%), lower soda (Na₂O ≤ 0.15%), higher alpha conversion (α-Al₂O₃ ≥ 94%), and greater density (≥ 3.94 g/cm³) compared to HA-1. These characteristics suit HA-2 for sensitive electronic components and high-purity technical ceramics.
A3: Yes, our deep processing facility can prepare customized particle sizes and grain distributions to meet specific customer requirements.
A4: Sodium ions increase electrical conductivity. Lowering Na₂O to ≤ 0.15% maximizes electrical resistivity, preventing leakage currents and thermal degradation in electronic assemblies.
