Alumina Slurry

Product Overview

Our high purity alumina slurry is a high-performance precision polishing medium made of high-quality alpha-alumina particles, featuring high hardness, good wear resistance and excellent chemical stability. It is formulated with advanced dispersion technology to ensure uniform particle size distribution and excellent suspension stability, suitable for various precision lapping and polishing processes of ceramic materials, optical glass, metals and semiconductor components, providing consistent and reliable polishing quality.

APPLICATION

Ceramic Component Manufacturing Optical Glass Processing Semiconductor Substrate Finishing Metal Surface Polishing Precision Instrument Production Medical Device Manufacturing Automotive Parts Production

Product Features

Precision Particle Size Grading
Narrow particle size distribution enables nanoscale, uniform material removal, yielding a scratch-free surface with consistent smoothness.

Optimized Cutting and Substrate Protection
Mohs hardness of approximately 9, providing high cutting efficiency without damaging precision or fragile substrates.

Superior Suspension Stability
Proprietary dispersion technology prevents particle sedimentation and agglomeration; only mild agitation is required before use, ensuring consistent polishing performance.

Environmentally Friendly and Easy Cleaning
Water‑based, non‑toxic, and heavy‑metal‑free formulation; readily removable with deionized water, leaving no residue or secondary contamination.

High Process Adaptability
Adjustable pH range from weakly acidic to weakly alkaline, non‑corrosive to a wide variety of substrates; compatible with both manual and automated equipment. Concentration and pH can be tailored to specific process requirements.

High Efficiency and Extended Service Life
Excellent polishing efficiency; waste slurry can be filtered and replenished with fresh solution for 3–5 cycles, significantly reducing operational costs.

Storage Conditions & Methods

1. Storage Conditions
Store in a cool, dry place at 5–35 °C in a tightly sealed container. Protect from direct sunlight, high temperatures, and freezing (below 0 °C may cause caking).
Shelf life: 6 months in unopened container; once opened, it is recommended to use within 3 months.
Keep away from strong acids, strong alkalis, and oxidizing agents. Store out of reach of children.

2. Instructions for Use
Shake thoroughly before use. Stirring for 5–10 minutes is recommended.

3. Safety Precautions
Wear safety goggles and acid/alkali‑resistant gloves during handling. Avoid contact with skin and eyes.
In case of accidental contact, rinse immediately with plenty of water. Seek medical attention for serious exposure.
Dispose of waste liquid in accordance with industrial wastewater regulations. Do not discharge directly into the environment.
