### What is the difference between porous and non-porous metals?

**1. What are porous metals?** .

Porous metals are materials that have small voids or holes within their structure, creating a porous or sponge-like appearance. These voids allow for the passage of liquids or gases through the metal, making it permeable.

**2. What are non-porous metals?** .

Non-porous metals, on the other hand, have a solid structure without any visible voids or holes. This means that non-porous metals do not allow for the passage of liquids or gases through their surface, making them impermeable.

**Explanation:** .

Porous metals have interconnected pores or voids that allow for the flow of fluids or gases through the material. These pores can be open or closed, depending on the specific type of porous metal. Common examples of porous metals include sintered metals, foams, and certain types of alloys.

Non-porous metals, on the other hand, have a dense and compact structure without any pores or voids. This means that fluids or gases cannot pass through the metal, making it impermeable. Non-porous metals are often used in applications where a sealed or solid structure is required, such as in piping, structural components, or electronic devices.

In summary, the key difference between porous and non-porous metals lies in their structure and ability to allow the passage of fluids or gases. Porous metals have interconnected voids that make them permeable, while non-porous metals have a solid structure that makes them impermeable. Both types of metals have their own unique properties and applications based on their structural characteristics.
