在Drickamer型高温高压实验装置的基础上,研制了一种新型的对顶式高温高压实验装置。为了增加样品体积和稳定容易地产生高压和高温,进行了各种改进。通过优化组件,如砧座,加热器,和垫圈,大样品体积约为4 mm 3(103倍以上,我们以前的设备获得的),实现了紧凑和轻的设备(外径40 mm;高度31 mm;重量300 g)。通过使用该组件,可以常规且稳定地实现高达约15 GPa和1700 K的压力和温度。为了进一步扩大压力范围,烧结金刚石被用作砧材料。结果,虽然样品体积减少到约1.3×10− 1 mm 3,但压力和温度达到约38 GPa和1400 K。
A new opposed-anvil high pressure and temperature apparatus was developed based on the Drickamer-type apparatus. Various improvements were made to increase the sample volume and to generate high pressure and temperature stably and easily. By optimizing components such as the anvil, heater, and gasket, large sample volumes of about 4 mm3(∼103times more than that previously obtained with our previous apparatus) were achieved, with compact and light apparatus (outer diameter ϕ 40 mm; height 31 mm; weight 300 g). Pressures and temperatures up to about 15 GPa and 1700 K can routinely and stably be achieved by using this assembly. In order to extend the pressure range further, sintered diamond was used as an anvil material. As a result, pressures and temperatures of around 38 GPa and 1400 K were achieved, although the sample volume was decreased to about 1.3×10−1mm3.
