Aluminium Oxides/Hydroxides TRIZ Cases
- Tailings Pond Liquor Carbonation for High-Purity Pseudoboehmite
Two-stage CO2 carbonation of alumina mud water controls pH to precipitate low-impurity pseudoboehmite while cutting waste and energy use.
- Alumina Particle Surface Treatment for Low Dielectric Loss
Heating alumina particles before surface treatment removes adsorbed moisture, helping mask OH groups and maintain low dielectric loss in resin compositions.
- Non-Spherical Alumina Fillers for Polymer Thermal Conductivity
Irregular alumina fillers enable dense packing and low viscosity at high loadings, achieving superior isotropic thermal conductivity.
- Fine Crystalline Boehmite Preparation via Acid-Treated Inoculant
Acid-milled inoculants enable hydrothermal crystallization to produce boehmite with controlled grain size and low surface area for plastic flame retardancy.
