Potassium hydroxide is strongly alkaline and corrosive. It is easy to absorb moisture in the air and deliquesce, and absorb carbon dioxide to form potassium carbonate. Dissolve in about 0.6 parts of hot water, 0.9 parts of cold water, 3 parts of ethanol and 2.5 parts of glycerin. When dissolved in water, alcohol or treated with acid, a lot of heat is generated. Today we'll look at the reasons for the high cost of solid potassium hydroxide.

　　1、由于固体氢氧化钾生产过程中需要煤炭烘烤，而且煤炭也急速飙升，所以制作成本也高；

　　1. Because the solid potassium hydroxide production process needs coal baking, and the price of coal also soars rapidly, so the production cost is also high;

　　2、产品的运输现在石油也在飙升，所以运费也在提高，当货物发到买家时比平时高出一些；

　　2. Now the price of oil is soaring, so the freight is also increasing. When the goods arrive at the buyer, the price is higher than usual;

　　3、由于液碱逐渐升高，所以制作烧碱的成本也相应的增高，所以固体氢氧化钾也增高。

　　3. As the price of liquid alkali increases gradually, the cost of making caustic soda also increases correspondingly, so the price of solid potassium hydroxide also increases.

　　以上就是固体氢氧化钾成本高的原因，另外氢氧化钾在工业上也叫活性阻燃剂、钠胶。根据它的结构特性，可以发现氧离子近似为立方面心紧密堆积，Al3+不规则地分布在由氧离子围成的八面体和四面体空隙之中。γ型阻燃剂不溶于水，能溶于强酸或强碱溶液，将它加热1200℃就全部转化为α型阻燃剂。

　　The above is the reason of high cost of solid potassium hydroxide. In addition, potassium hydroxide is also called active flame retardant and sodium gum in industry. According to its structural characteristics, it can be found that the oxygen ions are close packed in the cubic center, and Al3 + is irregularly distributed in the octahedral and tetrahedral spaces surrounded by oxygen ions. γ type flame retardant is insoluble in water and soluble in strong acid or alkali solution. When heated to 1200 ℃, it will be converted into α type flame retardant.
