In the rapidly evolving industries of photovoltaics, semiconductors, and advanced electronics, maintaining the purity of quartz materials is no longer a luxury—it’s a necessity. As these industries push technological boundaries, the quality of raw materials becomes increasingly critical. Among them, high-purity quartz (SiO₂ ≥ 98%) plays a foundational role in producing electronic-grade silicon and other precision components.
Unfortunately, traditional metal screening and conveying systems often fall short in these demanding applications. From frequent wear to material contamination, these issues drive up operational costs and compromise product quality. The answer? Silicon carbide (SiC) ceramic linings—a breakthrough material solution that ensures purity, durability, and operational efficiency across the board.
Before diving into the solution, it’s crucial to understand the importance of process integrity in quartz handling. The journey of quartz from raw mineral to refined powder or crystal involves several stages:
Screening and sorting for grain size uniformity
Conveying materials between processing stations
Calcination and refining to eliminate impurities
Any wear or contamination introduced during these steps can compromise the entire production batch. That’s why industries are increasingly turning to ceramic wear-resistant linings to prevent these issues before they begin.
Although metal has been the default material choice for decades, it is ill-suited for high-purity applications. Here’s why:
Metal components, especially in high-friction or high-impact zones, degrade quickly—often within 1 to 2 months. This leads to:
Frequent equipment shutdowns
Increased maintenance and labor costs
Supply chain disruptions
Metal debris—microscopic or visible—can flake off and mix with quartz, especially in vibratory screens or chutes. Even trace levels of contamination are unacceptable in industries like:
Solar energy production
Semiconductor wafer fabrication
Fiber optic manufacturing
During high-temperature processes like calcination, metal linings may oxidize or deform, introducing further contamination risks and mechanical failures.
Silicon carbide is an ultra-hard, chemically inert ceramic compound composed of silicon and carbon. It is thermally stable, wear-resistant, and chemically compatible with high-purity quartz materials.
Mohs Hardness of 9.2 – More than 15 times harder than high manganese steel
Thermal Resistance – Stable at temperatures exceeding 1,400°C
Chemical Inertness – Will not react with quartz or release contaminants
Eco-Friendly Burnout – Carbon elements volatilize as CO₂ during calcination
These characteristics make SiC the ideal choice for extending the life of screening and conveying systems while ensuring zero contamination.
SiC linings can last over a year, even in the most abrasive applications. This means fewer maintenance cycles, longer production runs, and lower costs.
Comparison:
| Material | Average Lifespan | Maintenance Frequency |
|---|---|---|
| High Manganese Steel | 1–2 months | Every 4–8 weeks |
| Silicon Carbide | 12–18 months | Once a year or less |
Since SiC is chemically similar to quartz and contains no metals, there’s zero risk of metallic contamination. This results in:
Higher product yields
Fewer rejections at quality control
Greater customer trust
Less frequent breakdowns and replacements lead to a 50% increase in production line stability. Processes become smoother, and equipment runs at optimal performance levels.
Companies have reported up to a 60% reduction in total maintenance costs after switching to SiC linings. The savings stem from:
Fewer part replacements
Lower labor costs
Less downtime
Sanxin’s SiC ceramic linings are custom-designed to fit various sections of quartz processing systems, depending on the wear dynamics and material flow patterns.
In areas subject to repeated mechanical stress—such as drop chutes or impact points—Sanxin installs SiC composite liners that absorb shock while resisting abrasion.
For areas like rotary screens and vibratory feeders, high-purity SiC plates provide a smooth, durable surface that protects both equipment and material.
Sanxin’s SiC ceramic pipes offer excellent resistance to abrasion during horizontal or vertical transport, ensuring minimal wear and high throughput.
High-purity quartz is the foundation for solar-grade silicon, which is then sliced into wafers and turned into solar cells. Metal contamination can reduce panel efficiency or lead to outright product rejection. SiC linings ensure:
Clean quartz transport
Stable process yields
Cost-effective solar cell manufacturing
The production of semiconductors demands ultra-high purity quartz powder. Even the smallest contamination particles can cause defects in chip fabrication. Silicon carbide ensures:
Absolute purity
Long-term reliability
Compliance with cleanroom manufacturing standards
Applications like fiber optics, LED wafers, and specialty lenses require quartz with extremely consistent properties. SiC linings help deliver consistent quality at scale.
