Sesquicarbonate Preparation TRIZ Cases
- NaOH CO2 Capture Conditions for Selective Carbonate Extraction
By tuning NaOH concentration and liquid temperatures, this case enables selective high-purity NaHCO3 or Na2CO3 extraction with lower energy loss.
- Sodium Bicarbonate Production via On-Site CO2 Capture
Generates carbon dioxide on-site by decomposing calcium carbonate in kilns, eliminating external transport logistics while maintaining product purity.
- Sodium Carbonate Crystallization Without Evaporation
Add solid sodium carbonate to aqueous bicarbonate solution for direct crystal separation.
- Silicon Wafer Oxygen Control for IGBT Gate Oxide Integrity
Controlled interstitial oxygen concentration below 7.0×10^17 atoms/cm³ prevents gate oxide integrity failure in insulated gate bipolar transistors.
- Melt Extrusion of Alkali Metal Bicarbonate Paste
Melt extrusion shapes alkali metal bicarbonate paste, eliminating costly crystallization and grinding steps while controlling particle properties.
- NHC-Pyridine Catalyst for Glycerol Dehydrogenation
A chelating N-heterocyclic carbene pyridine ligand complex stabilizes transition metal centers during glycerol conversion.
