Lignin Alkali
Alkaline lignin, also known as alkaline metal oxides, refers to compounds composed of alkaline metals (such as sodium and potassium) and oxygen elements. Their crystal structure exhibits the characteristics of ionic crystals.
Alkaline lignin refers to metal elements that can be used as alkaline substances in chemistry, typically including sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and radium (Ra). Alkaline lignin has the following properties:
1. Metallic properties: Alkaline lignin is a typical metallic element with metallic luster and conductivity. Their outer electronic structure is prone to losing one electron, forming a+1 valent cation.
2. Reactivity: Alkaline lignin is a highly reactive metal that can undergo violent reactions with many non-metallic elements, including oxygen, water, and halogens. They react with water to produce alkaline hydroxides.
4. Density: The density of alkaline lignin also increases with the increase of atomic number of the element. The density of sodium is 0.97 grams per cubic centimeter, while the density of cesium is 1.87 grams per cubic centimeter.
5. Existence in nature: Alkaline lignin exists in relatively few forms in nature and is relatively rare in ores or minerals. They mainly exist in the Earth's crust and typically exist in the form of salts or oxides.

Application:
Alkaline lignin has various important applications. Here are some common uses:
1. Dehydrating agent: Alkaline lignin has strong hygroscopicity and can be used as a dehydrating agent to absorb moisture from the air, thereby keeping the environment dry.
2. Fire extinguishing agent: Alkaline lignin releases a large amount of heat when reacting with water and is used in some fire extinguishing agents. They have the characteristics of rapid and efficient fire extinguishing.
3. Glass manufacturing: Alkaline lignin is an important raw material in glass manufacturing.
4. High energy batteries: Alkaline lignin is also used to manufacture some high-energy density batteries, such as alkaline batteries. These batteries use alkaline lignin as the anode material and generate electricity by reacting with ions in a conductive liquid.
