For more than two decades, Dalian Gaoteng has grown into a pillar of silica pebbles exports in the Chinese region. Already specialized in ceramic grinding media for over 20 years with our own mine and factory.

Gaoteng products are extensively exported and have established a strong presence across Southeast Asia, the Middle East, Europe, and beyond. This is also attributed to Gaoteng's strict control over product quality. From the extraction and selection of raw materials to the final quality control and packing, every link is filled with 100% meticulousness and effort. Meanwhile, due to the silica pebbles' characteristics, they can be used in various application fields:

1. Electronics: Powering the Digital World

Ultra-high-purity silica is fundamental to semiconductor manufacturing, the bedrock of modern electronics. So when grinding the raw materials, the silica grinding media should be of high purity and low wear loss. This can be used in the manufacturing of electronic devices such as integrated circuits, solar cells, and light-emitting diodes.

2. Glass Manufacturing: Achieving Clarity and Strength

Silica is the main material of glass, directly determining the product's transparency, chemical resistance, thermal stability, hardness, and strength. Our silica pebbles are the essential grinding media in ball mills, smashing the raw materials into fine powder and do not introduce impurities. Especially the glass-fiber industry.

3. Ceramic Industry: The Foundation of Quality

When most of the ceramics are produced, often use silica pebbles to grind ceramic raw materials, like clays, feldspars, silica, and kaolin, into slips or powders in ball mills. Iron contamination causes discoloration (reducing whiteness) and defects. Gaoteng's media grind efficiently without introducing impurities. Enables production of high-fineness ceramics (tiles, sanitaryware, tableware, technical ceramics) and brilliant white porcelain/vibrant glazes.

4. Refractory Materials:

Silica has high temperature stability and is widely used in the field of refractory materials. Grind all kinds of materials.

5. Fertilizer Industry: Enhancing Efficiency & Soil Health

Several fertilizer factories use flint pebbles to grind and mix chemical materials.

6. White Cement Industry: The Standard for Whiteness & Performance

Improve the hardening performance, fire resistance, physical properties, and chemical stability of cement. Steel media would cause catastrophic iron contamination. Gaoteng mine control ensures the essential low iron content, guaranteeing high whiteness (L* value).

7. Manufacture of fine chemicals: Enabling Precision & Purity

Silica can be used to prepare fine chemicals, such as catalysts and adsorbents.
