钾明矾作为固-液相变材料存在热传导性能差的缺点。
Aluminum potassium sulfate has has a disadvantage in poor thermal conductivity.
因为各种状态的钾明矾都能溶于水，当把它弄湿或接触湿皮肤时，会有一层肉眼看不见的细腻矿物层从钾明矾表面脱落，吸附到皮肤表面。
Since all forms of potassium alum are soluble in water, when the stone is wet or applied to wet skin, an invisible, fine layer of the mineral is rubbed off the stone and applied to the skins surface.
利用四川某含钾岩石制得的钾明矾进一步制备硫酸型钾氮肥和氢氧化铝，从原理、工艺等方面进行探讨，并通过中试解决了工业化生产所出现的问题。
The principle and process of producing potassium-nitrogen compound fertilizer and aluminium hydroxide from potash alum are studied. Some problems are solved through the pilot test.
但是你如果仅仅是为了以防万一，那不如你自己用硫酸铝钾或者明矾来自己制作一件。
So if you just want to be on the safe side, you can make one on your own by using aluminum potassium sulfate or alum for short.
在碳酸钾中，它变成黑色，而在明矾中一开始却什么反应都没有，直到煮沸后紫色都溢出来了。
In potash it turns black, but in alum nothing happens until you bring it to the boil, then purple colour comes flooding out.
采用硼酸和无水明矾及硫酸钾压块、焙烧、制备硼酸铝熔块。
Aluminium borate melting block was prepared by the combination of boric acid, anhydrous alum and potassium sulfate.
