sol-gel processes

The sol-gel process is a method for creating solid materials from liquids. It starts with a solution called a "sol," which contains tiny particles suspended in liquid. Over time, the sol undergoes chemical reactions that cause these particles to stick together, forming a network called a "gel." This gel can then be dried and heated to produce a solid material with specific properties, often used in coatings, ceramics, and glass manufacturing. The process allows precise control over the material's composition and structure, making it versatile for various applications.
