Calcium/Strontium/Barium Fluorides TRIZ Cases
- Lithium Recovery Process Using Bipolar Membrane Electrodialysis
Bipolar membrane electrodialysis separates lithium hydroxide from fluoride-bearing liquor while reusing the acidic stream for impurity stripping.
- Nitrogen-Bearing Phosphor Composition for Stable Red-NIR Emission
A nitrogen-bearing phosphor crystal maintains red to near-infrared brightness under high-energy excitation, improving LED emission stability.
- Lithium Sludge Recovery via LiF Precipitation and MVR Concentration
By precipitating LiF from lithium and fluoride sludge, then using MVR and recirculation, this case cuts waste solids and recovers lithium economically.
- Eu-Activated Phosphor Composition for Stable Red-NIR Emission
A Ba-Si-O phosphor host with Eu maintains red to near-infrared emission under UV or visible excitation with minimal brightness deterioration.
- Calcium Fluoride Seeded Crystallization for Fluorine Wastewater Recovery
Activated calcium fluoride seed crystals guide precipitation in fluorine wastewater to recover large, high-purity particles with less sludge.
- Halocarbon Conversion to Inorganic Salts via Metal Salt Reaction
Reacting halocarbons with metal salts produces inorganic halogen salts and carbon monoxide through high temperature chemical transformation.
- Stabilized Yttrium Oxyfluoride Powder for Plasma Resistance
Calcium fluoride suppresses phase transitions in yttrium oxyfluoride to prevent fracture and enhance halogen plasma resistance.
