In the ultrafine grinding process of electronic materials, precision ceramics, and new energy battery materials, the purity of the grinding medium often determines the quality of the final product. The mixing of trace impurities may lead to a decrease in product performance or even scrap. The SSA-995 high-purity alumina ball launched by NIKKATO Corporation in Japan, with a purity of 99.5% alumina and excellent wear resistance, is a leading powder processing product with high requirements

In the ultrafine grinding process of electronic materials, precision ceramics, and new energy battery materials, the purity of the grinding medium often determines the quality of the final product. The mixing of trace impurities may lead to a decrease in product performance or even scrap. Launched by NIKKATO Corporation in JapanSSA-995 high-purity alumina ballWith a purity of 99.5% alumina and excellent wear resistance, it provides a reliable grinding solution for the high demand powder processing field.

1、 Product positioning: High purity grinding media

SSA-995 belongs to the NIKKATO alumina ball product lineHigh Purity GradePositioned between the general grade (HD series, Al ₂ O3 93%) and high-purity high-performance grade (SSA-999W/999S, Al ₂ O3 99.9%).

The core positioning of this model is:While ensuring excellent wear resistance, it meets strict requirements for impurity control in application scenarios with higher puritySSA-995 is particularly suitable for grinding materials that are highly sensitive to impurities other than alumina, and can maintain the original purity of the material to a large extent during the grinding process.

2、 Core physical characteristics and technical parameters

SSA-995 alumina balls are made of high-purity alumina (Al ₂ O ∝ ≥ 99.5%) through precision sintering process, and have the following key performance indicators:

Data source: Technical documentation of NIKKATO products

1. High purity (99.5% Al ₂ O ∝)

The core advantage of SSA-995 lies in its high99.5% purity of aluminaThis means that during the grinding process, the wear of the medium itself will hardly introduce impurities other than alumina, making it particularly suitable for pollution sensitive applications such as electronic materials and high-purity powders.

2. High hardness and wear resistance

Vickers hardness reaches1,500 HV10Significantly higher than the general HD series (1100 HV10). This feature endows SSA-995 with excellent wear resistance and can maintain good sphericity during long-term grinding, reducing the frequency of medium replacement and further reducing the risk of impurity contamination.

3. High compressive strength

High compression strength3,000 MPaIt is 1.5 times higher than the HD series (2000 MPa). This enables SSA-995 to withstand higher intensity grinding impacts, making it less prone to breakage during high-energy ball milling or dispersion of high viscosity materials, ensuring the stability of the grinding process.

4. Excellent corrosion resistance and thermal stability

Aluminum oxide material has high corrosion resistance to corrosive media such as acid and alkali, and can operate stably for a long time in harsh chemical environments. Meanwhile, SSA-995 has good heat resistance and thermal shock stability, making it suitable for high-temperature grinding processes.

3、 Selection of specifications, dimensions, and forms

NIKKATO provides a wide range of specification options for SSA-995 to meet the particle size matching needs of different grinding equipment and processes:

SSA-995 covers a wide range of particle sizes, from 1mm small balls required for fine grinding at the micrometer level to 50mm large balls required for coarse crushing. Users can choose the appropriate medium size and grading scheme based on the initial particle size and target fineness of the grinding material.

4、 Applicable fields and scenarios

SSA-995 high-purity alumina balls are widely used in multiple industries that require high purity:

1. Electronic materials

• Grinding and dispersion of dielectric ceramics, piezoelectric materials, and magnetic materials

• Ultra fine grinding of electronic component substrate materials and sealing materials

• Fine Grinding of MLCC (Multilayer Ceramic Capacitor) Dielectric Materials

2. New energy battery materials

• Grinding and dispersion of positive electrode materials (such as lithium iron phosphate and ternary materials)

• Ultra fine treatment of negative electrode materials and solid electrolyte materials

3. High purity ceramic raw materials

• Grinding of advanced ceramic materials such as high-purity alumina and zirconia

• Raw material processing of precision ceramic components

4. Fine Chemicals and Pharmaceuticals

• High purity dispersion and grinding of pigments, coatings, and inks

• Fine crushing of catalyst support

• Grinding of drugs and food raw materials sensitive to metal ions

5. Glass and minerals

• Fine grinding of optical glass raw materials and high-performance glazes

• Ultra fine processing of non-metallic minerals such as high-purity quartz and kaolin

5、 Product series comparison and selection suggestions

For the convenience of selection, SSA-995 will be compared with other series of NIKKATO alumina balls as follows:

Selection Suggestions

1. Purity requirement assessmentIf the material is extremely sensitive to metal ions or other impurities (such as MLCC dielectric, battery materials), it is recommended to choose SSA-995 or higher purity SSA-999 series.

2. Grinding particle sizeCoarse grinding uses large balls of 15mm or more, fine grinding uses small balls of 1-10mm, and ultrafine grinding can consider the SSA-999S series (minimum 0.5mm).

3. Cost effectiveness considerationsFor conventional ceramic raw materials or scenarios with low purity requirements, the universal HD series can meet the needs; For high value-added products, the purity advantage of SSA-995 can effectively ensure product quality.

6、 Summary of Product Advantages

The core advantages of NIKKATO SSA-995 high-purity alumina balls can be summarized as follows:
