초록
Response surface methodology (RSM) was used to optimize the densification of Mg2SiO4 nanopowder prepared by Polyacrylamide gel method. The effects of monomer to salt molar ratio, calcination temperature and applied pressure on the densification of powders were investigated. The optimum operating conditions for densification were found to be monomer to salt molar ratio of 2.2, applied pressure of 563 MPa and calcination temperature of 784 o C. The obtained density under the optimum conditions determined by RSM was 98.1%.
