纤锌矿的物化性质 浅黄色、褐色或黑色(含铁越多,颜色越深)。条痕由无色至褐色。金刚光泽。单晶体成尖锥状,有的成短柱状或板状。集合体成纤维放射状。解理完全。密度4.0~4.3g/cm3。莫氏硬度3.5~4.0。常与闪锌矿共生。不溶于水,溶于酸。用于涂料、油漆、塑料等方面。具有松脂光泽或金刚光泽。单个的晶体成尖锥状,有的成短柱状或板状。集合体成纤维放射状。
英语翻译 This paper using sol-gel,acetic zinc Zn(CH3COO)2 2 H2O as raw material vanstone,anhydrous alcohol and ammonia solvent,polyethylene pyrrole(PVP)made for complexing agent precursor body solution,then use electrostatic spinning legal system for PVP/Zn(CH3COO)2 body precursor fiber,the calcination can achieve microporous structure of zinc oxide(ZnO)micro-nano fiber.On this basis,the single axis electrostatic spinning legal system for nanometer ZnO hollow fiber.Respectively by means of XRD and SEM on the preparation of the fiber content and morphology characterization.Test results show that:PVP/Zn(CH3COO)2 fiber surface smooth,diameter is about 300-700 nm,the metakaolin fiber diameter of 200 nm in left and right sides,XRD results show that the sintering process of ZnO for six edge fine zinc mine structure.Electrostatic spinning ZnO nano fiber and method for structure characterization(title)
红锌矿和纤锌矿有什么区别 纤维锌矿是一种较少见的硫化锌的矿物形式,以法国化学家Charles-Adolphe Wurtz的名字命名。其晶体结构是六角形晶体系统的一员且包含有四面等位的锌和硫原子形成ABABAB型。
纤锌矿的矿物基本信息 纤锌矿(wurtzite),ZnS。2113化学成分:Zn 67.1%(质量分5261数),S 32.9%(质量分数)。天然纤锌矿4102少见。晶体结构:2H 多形。六方晶系,点群6mm。空1653间群Pmc。具有纤锌矿型结构。晶格常数:a0=0.3820nm,b0=0.3820nm,c0=0.6260nm;α=90o,β=90o,γ=120o。Z=2。原子坐标:Zn,2b;2/3,1/3,0 S,2b;2/3,1/3,3/8
