From Sand to Silicon

Through a process called ion implantation (one form of a process called doping), the exposed areas of the silicon wafer are bombarded with various chemical impurities called Ions. Ions are implanted in the silicon wafer to alter the way silicon in these areas conducts electricity. Ions are shot onto the surface of the wafer at very high speed.

Sodium Silicate for Making Foundry Cores - Foundry Supplies

Sand is mixed with a binder to form a solid "sand core". A core must porous enough to allow gas to escape from the casting, while still blocking the molten metal. It should also be easily removed from the finished casting. Sodium Silicate is used as the binder that "glues" the sand together in cores. For example, imagine making a cannon.

The Metal Casting Process Explained | General Kinematics

Molding – To visualize the metal casting process so far, imagine yourself walking on the beach toward the ocean. Look at a footprint you leave behind in the wet sand. Your foot would be the core, and the impression left in the sand is a mold of your foot. Molding is a multistep process that will form a mold around the pattern using molding sand.

 · The traditional shell (hollow) core process uses a cast iron box that looks like the actual cylinder head. “After heating up the box and connecting a hose to it, sand is blown into the mold. The sand is impregnated with glue that’s activated by heat, so it solidifies when it comes in contact with the hot cast-iron mold,” Roberts said.
