• Core Processes: Precision quartz sheet cutting, double-sided lapping and polishing, edge chamfering, dimensional inspection

Client's Original Pain Points

1. Short Ceramic Dielectric Sheet Service Life, High Maintenance Costs

The client previously used alumina ceramic sheets as dielectric materials for their ozone generators. Under high-voltage, high-frequency discharge conditions, the ceramic sheets experienced surface micro-cracking and performance degradation due to prolonged thermal and electrical stress, with an average replacement cycle of only 6–8 months. Frequent shutdowns for replacement not only impacted the client's production line efficiency but also caused end-users (water treatment plants, semiconductor factories) to question equipment reliability.

2. Insufficient Discharge Uniformity, Fluctuating Ozone Yield

Due to limitations in the ceramic sintering process, batch-to-batch dielectric constant consistency was poor, resulting in uneven electric field distribution within the discharge chamber. The client reported ozone concentration fluctuations of up to ±15% across some discharge units, severely affecting the pass rate of water treatment disinfection effectiveness.

3. Impurity Leaching Contaminating Ozone Gas

Low-quality ceramic sheets exhibited trace metal element leaching (Al, Si, etc.) during discharge, posing contamination risks for semiconductor-grade high-purity ozone applications. The client was supplying ozone systems for a Russian semiconductor wet cleaning equipment manufacturer, and this issue directly prevented them from meeting end-user purity requirements.

Our Targeted Solutions & Advantages

1. High-Purity Quartz Material with Superior Dielectric Properties

We selected high-purity fused quartz sheets (SiO₂ ≥ 99.9%) offering high dielectric strength, low dielectric loss, and excellent chemical stability. Quartz operates at only 1/5 to 1/6 of its breakdown voltage, providing outstanding high-voltage tolerance and ensuring long-term stable discharge chamber operation. Industry data confirms that ozone generators using quartz dielectric modules can achieve 10-year maintenance-free performance.

2. Low Hydroxyl Content, No Devitrification at High Temperatures

We select low-hydroxyl quartz material (OH content ≤ 5 ppm) that maintains structural stability in high-temperature regions generated by high-voltage discharge, with no surface devitrification or dielectric performance degradation, achieving service life exceeding 20,000 hours.

3. Fast Delivery Breaking European Supplier Monopoly

Our standard order delivery cycle is 7–12 working days, significantly superior to European suppliers' 8–10 week lead times. The client can substantially reduce inventory pressure and respond flexibly to end-market demands.

Cooperation Results & Client Feedback

1. Ozone Yield and Concentration Stability Significantly Improved

After switching to Shengfan quartz sheets, ozone concentration fluctuations narrowed from ±15% to ±3%, with ozone conversion efficiency increasing by approximately 12%. The water treatment end-user reported disinfection effectiveness pass rate improvement from 92% to 99.5%.

2. Equipment Maintenance Cycle Substantially Extended

After adopting quartz dielectric sheets, the ozone generator has operated continuously for over 12 months without dielectric component replacement (compared to the previous 6–8 month average with ceramic sheets). Maintenance frequency was reduced by over 40%, and the client's total operational and maintenance costs decreased by approximately 25%.

3. Semiconductor-Grade High-Purity Ozone Application Certified

Low-impurity quartz sheets ensured ozone gas purity met required standards. The client's semiconductor wet cleaning ozone system successfully passed certification with a Russian wafer foundry, opening access to a previously unattainable high-end market segment.
