XLW Chemical's high-purity phosphoric acid (85%) is refined using a thermal process, achieving a breakthrough in heavy metal content of ≤0.5ppm. Its non-volatile properties ensure no acid mist corrosion in high-temperature production lines. The proprietary three-stage purification technology (Patent No. ZL2023 8 076543X), certified to ISO 21437 standards, offers an environmentally friendly solution with three times the efficiency of wet-process phosphoric acid for phosphate fertilizer production, semiconductor etching, and metal surface treatment.

Addressing Five Key Industrial Challenges

✅ Fertilizer caking and failure

Low fluorine design (F ≤ 0.1%) prevents ammonium phosphate salt crystallization and hardening

Jiangsu compound fertilizer plant tested finished product moisture content ↓35%

✅ Uneven semiconductor etching

Nano-level filtration (0.1 μm) eliminates particle trailing

Etching uniformity >98% (silicon wafer tested)

✅ Metal rusting during processing

Self-generated iron phosphate protective film (film thickness 2–5 μm)

Salt spray test >500 hours without rusting 48

✅ Acid mist corrosion of equipment

Vapor pressure <0.03 mmHg (80°C)

Electroplating workshop equipment lifespan extended by 3 times

✅ Environmental penalty risk

No arsenic/cadmium emissions (compliant with EU 2023/457)

Wastewater treatment costs reduced by 62%

Golden application scenarios

Core raw material for phosphate fertilizers

Direct synthesis of diammonium phosphate (DAP)

Characteristics: Reaction speed 40% faster than wet acid method

Metal surface treatment

Pre-treatment for aluminum anodization

Case study: Tesla battery casing process yield increased by 23%

Electronic semiconductor etching

Selective etching of GaAs wafers (selectivity ratio > 100:1)

Certified to SEMI F40 ultra-high purity standards

Industrial cleaning systems

Calcium scale removal from food machinery (compliant with FDA 21 CFR 173.310)

Safer alternative to nitric acid
