基于铰链式六面顶压机的二级6-8模超高压大腔体内置加热元件的设计与温度标定

 首次报道了一种新型的基于铰链式六面顶压机的二级6-8模大腔体静高压装置的内置加热元件的设计与温度标定。此加热组装结构简单，升温快，保温效果好，并有效地解决了国外基于两面顶压机构架下的二级6-8模内加热组装中热电偶在施加压力时易断的问题。以低成本的碳管为加热元件，采用直接和间接两种加热方式，用双铂铑（Pt6%Rh-Pt30%Rt）B型热电偶进行温度测量，并根据实验过程中加热功率与腔内实际温度的关系，对不同压力下腔体内的温度进行了标定。实验结果表明：此加热系统的油压达到40 MPa（腔体压力约10 GPa）时，温度可以达到1 700 ℃以上；在油压为30 MPa、样品室温度为1 000 ℃时，保温时间可达2 h，甚至更长；实验中获得样品的直径可达3 mm，高度可达7 mm，实现了在高温超高压条件下大样品的制备，满足了实验对产生高温超高压条件的需要。

Design and Temperature Calibration for Heater Cell of Split-Sphere High Pressure Apparatus Based on the Hinge-Type Cubic-Anvil Press

A new type of heater cell for the split-sphere high pressure apparatus based on the hinge-type cubic-anvil press was reported.This heating apparatus has the advantages of being simple,low cost,fast temperature rising,good heat insulation,and the temperature signal can be easily extracted.Carbon tube was used as a heating element for side-heating in our experiments.The size of the sample in the cell can reach 3 mm in diameter,and 7 mm in height.The relationship between the heating electric power and cell tem...
