A ceramic proppant was created in an Al2O3-CaO-MgO-SiO2-Sc2O3 (ACMSS) system to increase acid resistance. The impacts of corrosion on the properties of proppants were investigated using a 12wt% HCl +3wt% HF acid mixture. The microstructure and phase of samples were analyzed. The acid resistance of silicon-containing alumina ceramic can be effectively improved by adding Sc2O3. The results show that...
The acid resistance of fracturing proppant can be effectively improved by reducing SiO 2 . An acid-resistant silicon-free ceramic proppant was created in an Al 2 O 3 –BaO–CaO–MgO (ABCM) system to increase the proppant's acid resistance. The effects of corrosion on the properties and microstructure of the proppant were investigated using a 12wt% HCl+3wt% HF acid mixture. The...
