2. Powder metallurgy - Wikipedia

   en.wikipedia.org/wiki/Powder_metallurgy

   Iron powder is commonly used for sintering. Powder metallurgy (PM) is a term covering a wide range of ways in which materials or components are made from metal powders.PM processes are sometimes used to reduce or eliminate the need for subtractive processes in manufacturing, lowering material losses and reducing the cost of the final product.

3. Hot pressing - Wikipedia

   en.wikipedia.org/wiki/Hot_pressing

   Hot pressing is a high-pressure, low-strain-rate powder metallurgy process for forming of a powder or powder compact at a temperature high enough to induce sintering and creep processes. [1] This is achieved by the simultaneous application of heat and pressure. Hot pressing is mainly used to fabricate hard and brittle materials.

4. Face powder - Wikipedia

   en.wikipedia.org/wiki/Face_powder

   Loose face powder in three different shades. Face powder is a cosmetic product applied to the face to serve different functions, typically to beautify the face. Originating from ancient Egypt, [citation needed] face powder has had different social uses across cultures and in modern times, it is typically used to set makeup, brighten the skin and contour the face.

5. Hot isostatic pressing - Wikipedia

   en.wikipedia.org/wiki/Hot_isostatic_pressing

   Isostatically pressed [clarification needed] nickel alloys. Hot isostatic pressing (HIP) is a manufacturing process, used to reduce the porosity of metals and increase the density of many ceramic materials. This improves the material's mechanical properties and workability. The process can be used to produce waste form classes.

6. Sintering - Wikipedia

   en.wikipedia.org/wiki/Sintering

   Pressureless sintering is the sintering of a powder compact (sometimes at very high temperatures, depending on the powder) without applied pressure. This avoids density variations in the final component, which occurs with more traditional hot pressing methods.

7. Powder - Wikipedia

   en.wikipedia.org/wiki/Powder

   A powder is a dry solid composed of many very fine particles that may flow freely when shaken or tilted. Powders are a special sub-class of granular materials, ...
