You know how sometimes your ice cubes fuse together in your glass leading to a hilarious pour-crap-all-over-your-face moment? Or how that bag of ice in your freezer becomes one huge ice block, causing you to take an ice pick to it and accidentally poke a hole in your freezer? Well, that's a result of a process called sintering, and it's the same process used in industrial applications to mold metals, such as Tungsten, that have extremely high melting points without actually having to heat the material to said melting point.
