Optimization solutions for ITO target material and substrate welding porosity issues include: 1) Plasma cleaning (Ar/O₂ = 4:1, 300W) to remove surface oxides (O content reduced by 85%); 2) Gradient heating welding (200°C → 450°C stepwise holding, total duration 60…
Effective solutions to improve the creep resistance of bismuth-based low-temperature solders include: 1) Nanoparticle doping (e.g., 3% Al₂O₃ doping reduces the steady-state creep rate to 2.4×10⁻⁸ s⁻¹); 2) Multi-element alloying (Bi-20Sn-0.5Ag can increase the stress exponent n from 4.2 to…
Key technologies to increase the hydrometallurgical leaching rate of indium from liquid crystal panel waste to over 90% include: 1) Mechanical-thermal synergistic pretreatment (ball milling particle size ≤20μm, pyrolysis temperature 450℃); 2) Hydrochloric acid-hydrogen peroxide (HCl 4mol/L + H₂O₂ 0.5mol/L)…
Innovative paths for germanium recycling enterprises to enhance competitiveness include: 1) Multi-source synergistic recycling technology (co-production from zinc slag/coal ash/fiber waste, increasing germanium enrichment efficiency by 5 times); 2) Selective organophosphonic acid extraction process (Ge recovery rate >99.5%, separation factor…
The core pathways for optimizing tin recovery processes using ultrasonic-assisted leaching technology include: 1) Cavitation effect enhancing interfacial reactions (micro-jet pressure >20MPa, leaching rate increased by 3 times); 2) Low-frequency high-power ultrasound (20kHz², leaching time shortened from 8h to 1.5h);…
