研制了TiC-MgO复合材料作为多砧高压装置X射线研究的加热元件。我们合成了TiC-MgO块体（50-70 wt.% TiC）通过在冷等静压机中压缩，随后在气流炉中烘烤而形成。用车床或数控铣床加工出管状加热器。如此生产的加热元件已被证明在10 GPa下产生高达2250 K的温度，由于石墨-金刚石转变，经典的石墨加热器不再适用。 这些新的加热器已被成功地用于原位X射线照相和衍射测量液态铁合金，利用良好的X射线透明度。
TiC-MgO composite was developed as a heating element for X-ray study in the multi-anvil high pressure apparatus. We synthesized TiC-MgO blocks (50–70 wt.% of TiC) by compression in a cold isostatic press followed by baking in a gas flow furnace. Heaters of tubular shape were manufactured from the synthesized blocks either by lathe or numerically controlled milling machine. The so-produced heating elements have been proved to generate temperatures up to 2250 K at 10 GPa, condition where classical graphite heaters are not suitable anymore due to graphite-diamond transition. These new heaters have been successfully used forin situX-ray radiography and diffraction measurements on liquid Fe alloys, exploiting excellent X-ray transparency.
