They then treat the material with a sodium potassium alloy. Micrograph of mesoporous silicon with sodium chloride and potassium chloride salts embedded in the matrix. Once the bonds break, the chlorine binds with the sodium, potassium and silicon, potassium chloride and sodium chloride—table salt—become solid, forming a material composed of crystals of salt embedded in silicon. There are some processes that use sodium potassium alloy at industrial levels.
