potassium oxide

A change of the solvent for samples in determination of sodium oxide and potassium oxide with flame photometry

火焰光度法测定氧化钠、氧化钾溶剂的改变

Some physical, chemical and electrical properties were measured, it is showed that main performances of the glasses were improved, when sodium oxide replaced part of potassium oxide in the glasses of K2_O-ZnO-SiO_2 system.

结果表明，在K2O-ZnO-SiO2系统中以Na2O取代部分K2O后，玻璃的主要性能得到改善。

The influence of amount of potassium oxide addition, heating temperature, holding time and cooling mode on crystallizability of and dissolution rate of potassium from potash fertilizer were investigated.

考察了氧化钾加入量、加热温度、保温时间以及冷却方式对合成钾肥结晶性能和钾元素溶出率的影响。

At space, the content of potassium oxide ( K_2O) is as many as that of the basalt of Japan Sea rift belt, but is much higher than that of Japan Island arc.

在空间上，K2O的含量大体与日本海裂谷带玄武岩相当，而远远高于日本岛弧玄武岩的含量。

无机物：氮化铝、二氧化锆、氟化钾、膨润土、高岭土、硫酸钡、硫酸钻、铝酸钠、氧化铬、钛白粉。

Potassium hydroxide is frequently called caustic potash, and in the fertilizer industry, potassium oxide is called potash.

氢氧化钾常被称为腐蚀性碳酸钾，在肥料工业中，也把氧化钾称作钾碱。
