Fused Silica Micropowder Production Systems and Processing Lines

Program Overview

This solution focuses on the industrialized production of fused silica micropowder, producing fused silica micropowder with high purity, low expansion coefficient and excellent thermal stability by integrating the core processes of raw material treatment, high-temperature melting, rapid cooling, fine crushing and grading and purification. The system is designed to be mature and reliable, and is suitable for electronic packaging, high-end ceramics, specialty coatings and other fields with stringent requirements on material properties.

Process Flow

1. Raw Material Selection

   • Multi-stage purification of quartz raw materials

   • Deep removal of impurities through magnetic separation, flotation and other processes.

2. High-temperature electrofusion refining

   • High temperature melting in electric arc furnace

   • Melting temperature reaches more than 1750℃

   • Ensure complete melting and homogenization of raw materials

3. Rapid cooling treatment

   • Adopt water quenching or gas quenching rapid cooling process

   • Formation of amorphous silica glass

4. Fine crushing and grinding

   • Multi-stage mechanical crushing to the required particle size

   • Fine grinding by air flow mill

5. Precision Classification System

   • Multi-stage airflow classification ensures concentrated particle size distribution.

6. Iron removal and purification

   • High gradient magnetic separation to remove magnetic impurities

   • Ensure that the iron content in the product meets the standard

7. Finished product packaging and storage

   • Automated packaging in a clean environment

   • Moisture-proof and pollution-proof storage conditions

System Characteristics

• High purity assurance: deep purification of raw materials, product purity up to 99.9% or more
