Embodiment Construction
[0013] 0.36g of polyvinylpyrrolidone (PVP K-30) was dissolved in 100ml of ethylene glycol as a reaction medium, 1mmol of antimony trichloride and 3mmol of potassium ethylsulfonate were introduced into the above-mentioned solvent respectively, stirred to obtain a homogeneous liquid phase, and then Transfer to a 140ml polytetrafluoroethylene plastic-lined reaction kettle, seal it, and react at 150-250°C for 12 hours. After cooling, wash it several times with distilled water, ethanol, etc., and dry it in vacuum. The obtained product is yellow to red. Zodiac powder, proved to be KSb by powder diffraction (XRD) and energy spectrum 5 S 8 .
