Sintering compacts powdered material, usually a metal or a ceramic, and heats it below its melting point until the individual particles fuse at their points of contact into a single solid mass, producing a finished part without the material ever fully liquefying.

Facts
Disputed
Origin Year
1909 1
Sintering itself is ancient: fired ceramics and early sintered-iron and platinum-alloy artifacts predate any written record of the process by millennia. The 1909 date marks a narrower milestone, William Coolidge's patented process for sintering tungsten powder into a ductile wire for incandescent lamp filaments at General Electric, usually cited as the point sintering became a deliberately engineered industrial process for metals rather than an inherited craft technique.
Core Principle
Heat a compacted mass of powder below its melting point until the particles bond at their points of contact into one solid piece, without the material ever becoming fully liquid. 1

Sintering or frittage is the process of compacting and forming a solid mass of material by pressure or heat without melting it to the point of liquefaction.

Open Questions (1 open question)
Should sintering's origin be dated to its ancient craft use in fired ceramics and early sintered-metal artifacts, or to William Coolidge's 1909 patented process, the point it became a deliberately engineered industrial technique?

Ancient artisans achieved sintering empirically without understanding or naming the underlying process, so the entity's single origin-year property cannot represent both an ancient craft practice and a specific engineering milestone at once.

What would resolve this A convention for whether this atlas's "origin-year" property means first craft use or first deliberate engineering formalization would settle which date belongs on this fact, consistent with how the atlas already treats other ancient-craft-to-modern-engineering methods.
