摘要： 以金属镁、钛、锆和钨以及升华硫为原料,通过温度梯度法合成了硫化镁、硫化钛、硫化锆和硫化钨,并利用X射线衍射分析了合成物的矿物组成,研究了合成体系内升华硫的蒸发量与合成体系容积大小、合成温度以及合成体系抗压强度等参数间的关系·研究结果表明,在本实验条件下,合成体系内的最大升华硫蒸发量应为1 15g,并根据此硫蒸发量控制合成体系内的温度梯度和升温速度,安全且大量地合成了硫化镁、硫化钛、硫化锆和硫化钨,其质量分别为56 37,112 00,155 36和247 97g·

Abstract: MgS, TiS2, ZrS2 and WS2 were synthesized by temperature gradient method using Mg, Ti, Zr, W and sublimed sulfur as raw materials. The mineral compositions of the synthesized sulfides as above were determined by X-ray diffraction. Relationships among the evaporating loss of sublimed sulfur and such parameters as volumetric size, synthesizing temperature and compression strength of the synthesized sulfides were studied. The results showed that the maximal evaporating loss of sublimed sulfur is 1.15 g in the synthesizing process under the same experimental conditions. Then, based on the evaporating loss of sublimed sulfur, the temperature gradient and heating rate in the synthesizing process were controlled, to synthesize safely large quantities of MgS, TiS2, ZrS2 and WS2 with their masses up to 56.37 g, 112.00 g, 155.36 g and 247.97 g respectively.
