摘要: A new laboratory method has been suggested for synthesizing coesite in the Earth’s crust by considering similar characteristics of local collisions and shearing strength between earth’s plates high-energy mechanical ball milling (MBM),combining high static pressure temperature technique,and using mixtures α-quartz graphite as initial materials, which Silicon is mixed best quality ratio. The lowest condition 3.8GPa 873K. Keywords-α-quartz-graphite ; Coesite; High pressure.
