Lithium compounds have many uses. The most notable of these is the lithium hydride, lithium hydride. When lithium metal and hydrogen act, a white lithium hydride powder is formed. Lithium hydride can react violently with water to release a large amount of hydrogen. One kilogram of lithium hydride and water can release 2,800 liters of hydrogen! Therefore, lithium hydride can be regarded as a convenient "warehouse" for storing hydrogen. Two kilograms of lithium hydride and water release hydrogen, which is equivalent to a hydrogen gas contained in a common hydrogen steel cylinder with a pressure of 120 to 150 atmospheres. Lithium hydride is also an important raw material for thermonuclear reactions. In addition, some compounds of lithium are also used as glazes in the ceramic industry. In the glass industry, it is used to make opal glass and special glass that can pass ultraviolet rays. The screen glass of a TV set is lithium glass. The addition of lithium hydroxide to the alkaline circuit battery can greatly increase its capacitance.


In plants, compounds of lithium are often encountered. However, their treatment of plants is not yet fully understood. Some red and yellow seaweeds and tobacco often contain more lithium compounds. When the tobacco is burned to ashes, lithium is left in the ashes. Lithium can be used as a catalyst to accelerate some chemical reactions. What's interesting is that you light the match and put the candy on the flame of the match, when the sugar just starts to melt, but it doesn't burn. However, if you sprinkle some cigarette ash on the candy, then the candy will burn like paper! This is because lithium ash in the cigarette ash can accelerate the oxidation (burning) reaction of the sugar.
