【摘要】：基于國產(chǎn)鉸鏈式六面頂壓機二級6-8型靜高壓裝置,采用去尖3節(jié)式36/20結(jié)構(gòu),設(shè)計了一種"橋式"結(jié)構(gòu)的石墨加熱組裝,通過高壓原位溫度測量獲取加熱功率與溫度的對應(yīng)關(guān)系,得到了穩(wěn)定的p-T(2.5~10.4GPa,0~1 650/1 800℃)區(qū)域。同時樣品腔體直徑可以達到13mm,實現(xiàn)了厘米級大樣品的高溫高壓制備。討論了組裝的電阻與溫度之間的關(guān)系,并分析了電阻變化的原因。通過對樣品燒結(jié)情況的表征,來反映腔體的溫度分布情況。研究工作對基于國產(chǎn)鉸鏈式六面頂壓機的二級6-8型靜高壓裝置的加熱設(shè)計有一定的參考意義,并具有良好的實用性。
[Abstract]:Based on the two-stage 6-8 static high pressure device of the domestic hinged six-sided top press, a "bridge" structure of graphite heating assembly was designed with the structure of removing the tip and three knots, and the corresponding relation between heating power and temperature was obtained by high pressure in-situ temperature measurement. The stable p-T (2.5 ~ 10.4 GPA _ 0 ~ (1 650 / 1 800 鈩，
