Nano-sized barium strontium titanate (BaxSr1-x TiO3, BST) powders were synthesized with hydrothermal and solvothermal methods at 120 ℃ for 4 h based on the rea
High molar ratio potassium silicate solution used in zinc-rich water-base coatings was prepared by adding the nanosize SiO2 to the low molar ratio potassium sil
