na2so4·10h2o

俗称芒硝(mángxiāo)

mirabilite

也作硭硝。含有结晶水的硫酸钠的俗称。化学式na2so4·10h2o。

无色晶体,易溶于水。用于制革、制玻璃、制碱工业等,也用作泻药。

硫酸盐类矿物芒硝,经加工精制而成的结晶体。

【性状】单斜晶系,晶体呈短柱状或针状;通常成致密块状、纤维状集合体。无色或白色,玻璃光泽,具完全的板面解理,莫氏硬度1.5~2,比重1.48。味清凉略苦咸,极易潮解,在干燥的空气中逐渐失去水分而转变为白色粉末状的无水芒硝。本品为棱柱状、长方形或不规则块状及粒状。无色透明或类白色半透明。质脆,易碎,断面呈下班样光泽。无臭,味咸。

【产生】产于干涸的盐湖中,与石盐、石膏等共生。现代芒硝矿床产于内陆湖泊和海滨半封闭的海湾潟湖里,在干燥炎热的条件下,温度在33℃以上蒸发时,形成无水芒硝;在33℃以下或秋冬气温下降时,形成芒硝。世界上芒硝湖的分布以中国和前苏联较多,中国主要分布在西藏 、内蒙古、黑龙江 、山西、吉林等省、区。古代芒硝矿床产在陆相湖泊沉积岩系里,一般在红色砂页岩系中呈透镜状产出。中国湖北省的储量居全国之首。工业矿物原料所指芒硝,常包含无水芒硝和钙芒硝,用以制取硫酸铵、硫酸钠、硫酸及硫化钠等化工原料。其中用于制造洗衣粉的芒硝占总用量的65%~70%。

【性味与归经】咸、苦,寒。归胃、大肠经。

【功能与主治】泻热通便,润燥软坚,清火消肿。用于实热便秘,大便燥结,积滞腹痛,肠痈肿痛;外治乳痈,痔疮肿痛。

用法及用量:6-15克,不入煎剂,以药汁或开水溶化后服。外用适量,包敷患处。

【注意】孕妇禁用。

【贮藏】密闭,在30℃以下保存,防风化。

【别名】 硫酸钠,芒硝 【外文名】sodium sulfate 【适应症】 1.用于便秘、肠内异常发酵,亦可与驱虫剂并用;与活性炭合用,可治疗食物或药物中毒。 2.用于阻塞性黄疸及慢性胆囊炎。 3.用于惊厥、子痫、尿毒症、破伤风、高血压脑病及急性肾性高血压危象等。 4.也用于发作频繁而其他治疗效果不好的心绞痛病人,对伴有高血压的病人效果较好。 5.外用热敷,消炎去肿。 【用量用法】 【规格】每次15~20g,便秘可用3%~5%水溶液,于清晨空腹服。
