Sintered glass is a porous material created by fusing glass particles at high temperatures without fully melting them. It serves multiple functions, primarily in filtration, diffusion, and separation processes. Its uniform porosity and chemical resistance make it ideal for laboratory and industrial applications, such as filtering liquids and gases, controlling gas flow, and supporting catalysts. Sintered glass is also used in analytical chemistry for precise separations and in medical devices for controlled drug delivery. Its durability, thermal stability, and inertness to most chemicals make it a versatile material in scientific and industrial settings.
Key Points Explained:
-
Filtration
- Sintered glass is widely used as a filter medium due to its uniform pore structure.
- It effectively separates solid particles from liquids or gases, making it essential in laboratory settings for tasks like purifying solvents or sterilizing solutions.
