Ceramic balls uses

Preface

Ceramic balls have a wide range of uses. They are mainly spherical products made of materials such as alumina, zirconia, and silicon nitride. With their high strength, high hardness, wear resistance, corrosion resistance, high-temperature resistance, and good insulation, the following is a detailed classification and application introduction.

Classification and Uses

Inert ceramic balls: Used as support and covering materials in chemical towers, their main functions include: increasing contact area, distributing gases or liquids, and protecting catalysts

Ceramic balls for bearings: Ceramic balls (such as silicon nitride and zirconia) are characterized by high hardness, wear resistance, high-temperature resistance, and corrosion resistance. They are commonly used in high-speed precision bearings, vacuum equipment, and rolling components in high-temperature environments.

Grinding ceramic balls: High-strength ceramic balls are used in grinding equipment, such as ball mills and sand mills, to grind materials. It is applied in industries such as coatings, ceramics, electronic materials, and pharmaceuticals. Commonly used materials include zirconia balls and alumina balls

What are the differences in performance among different types of ceramic balls?

The performance of different types of ceramic balls varies significantly: alumina ceramic balls offer high cost performance. Their hardness and temperature resistance increase with the content of alumina. They are resistant to acid and alkali corrosion (except for strong hydrofluoric acid), but have relatively low toughness. Zirconia ceramic balls have the best strength and toughness, strong resistance to impact and wear, good biocompatibility, poor thermal conductivity and medium temperature resistance. Silicon nitride ceramic balls are heat-resistant, have stable wear resistance at high temperatures, excellent corrosion resistance, and a relatively low density. Silicon carbide ceramic balls have the highest hardness and wear resistance at room temperature, the best thermal conductivity, resistance to almost all chemical corrosion, and extremely strong heat resistance, but they are relatively brittle. Silicate ceramic balls are known for their excellent wear resistance and chemical inertness, and are suitable for general grinding and filling scenarios.

In conclusion：the applications of ceramic balls cover multiple fields ranging from basic industries to high-end technologies. Their performance advantages make them an ideal choice to replace traditional metal and plastic balls, especially in extreme environments or scenarios with high requirements for precision and lifespan.
