【摘要】 白云石具有较高的热膨胀系数，较低的热导率和稳定的高压物相。用它制成金刚石合成的高压腔内村，可以减少腔内压力梯度，屏蔽矿物成份及杂质进入高压腔，提高金刚石合成效果．更多还原

【Abstract】 Dolomite is featured with greater heat expansive factor,lower heat conductivity and stable physi-cal phase under high pressure。The olomite liner for the high pressure chamber of diamond synthesis can reducethe pressure gradient in the chambershield the mineral components and impurities out of the high pressurechamber and increase diamond svnthesis efficiencv。更多还原
