Phosphorus Oxides TRIZ Cases
- Use of long-chain phosphoric acid esters in aqueous polyurethane dispersions
See how long-chain phosphoric acid esters replace ammonium stearate to prevent surface blooming
- Binary-Substituted Vanadium Phosphate Cathode for Fast-Charging Stability
Binary metal substitution and halide tuning improve sodium-ion cathode conductivity, capacity, and cycle life while lowering vanadium cost.
- Lithium Difluorophosphate Synthesis With Phosphorus Reagents for Higher Yield
Phosphorus oxides or phosphate lithium salts replace silicon-based routes, boosting lithium difluorophosphate yield through solvent removal and sealed reaction.
- Binary-Substituted Vanadium Phosphate Cathode for Low-Cost Sodium-Ion Cells
Aluminum and fluorine substitution lowers vanadium use while improving conductivity, rate capability, and cycle stability in sodium-ion cathodes.
- Lithium Difluorophosphate Production With Solvent Removal for Higher Yield
A hydrocarbon-solvent route with partial solvent removal boosts lithium difluorophosphate yield and purity for lithium-ion electrolyte use.
- Packed-Bed Phosphorus Production for High-Purity Low-Energy Recovery
A carbon packed bed followed by a condensation accelerator bed enables stable, high-purity liquid phosphorus production at lower energy.
- Rotary Kiln Phosphorus Recovery from Sewage Sludge with Iron Control
A rotary kiln adapts the Hard process to recover over 80% phosphorus from sewage sludge by tuning reactant ratios, temperature, and residence time to limit iron interference.
- P4O6 Production with Vapor Recycle and Byproduct Recovery
A vapor recycle stream and quench-based reactor process raises P4O6 yield and purity while recovering byproducts for phosphoric acid production.
- Integrated Heat Recovery for Furnace-Process Phosphoric Acid
An economizer links phosphorus burning and hydration towers to recover heat together and generate medium-high-pressure steam.
- Fluoroapatite Production via Hydrogen Fluoride pH Control
Replacing ammonium hydrogen fluoride with hydrogen fluoride eliminates ammonia impurities, enabling high crystallinity and acid resistance in fluoroapatite.
