Mesoporous silica powder for dental restoration composites from rice husk: a green sol–gel synthesis
Morphologically organized non-crystalline silica powder was synthesized from rice husk by a green sol–gel route. Amorphous sphere-shaped silica powder with a surface area of ~ 370 m2 g−1, particle size in the range of 70–250 nm and pore size of ~ 8 nm was synthesized using sodium silicate extracted...
