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、由于固體氫氧化鉀生產(chǎn)過程中需要煤炭烘烤，而且煤炭也急速飆升，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、產(chǎn)品的運輸現(xiàn)在石油也在飆升，所以運費也在提高，當貨物發(fā)到買家時比平時高出一些；

　　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、由于液堿逐漸升高，所以制作燒堿的成本也相應的增高，所以固體氫氧化鉀也增高。

　　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.

　　以上就是固體氫氧化鉀成本高的原因，另外氫氧化鉀在工業(yè)上也叫活性阻燃劑、鈉膠。根據(jù)它的結(jié)構(gòu)特性，可以發(fā)現(xiàn)氧離子近似為立方面心緊密堆積，Al3+不規(guī)則地分布在由氧離子圍成的八面體和四面體空隙之中。γ型阻燃劑不溶于水，能溶于強酸或強堿溶液，將它加熱1200℃就全部轉(zhuǎn)化為α型阻燃劑。

　　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.
