Boiling Chips - Organic Chemistry

Boiling Chips. Boiling chips are small, insoluble, porous stones made of calcium carbonate or silicon carbide. These stones have pores inside which provide cavities both to trap air and to provide spaces where bubbles of solvent vapor can form. These bubbles ensure even boiling and prevent bumping and boiling over and loss of the solution.

silicon | Element, Atom, Properties, Uses, & Facts

When silicon and carbon are coined at electric furnace temperatures (2,000–2,600 °C [3,600–4,700 °F]), they form silicon carbide (carborundum, SiC), which is an important abrasive. With hydrogen, silicon forms a series of hydrides, the silanes. When coined with hydrocarbon groups, silicon forms a series of organic silicon compounds.

Boiling chip - Wikipedia

A boiling chip, boiling stone, porous bit or anti-bumping granule is a tiny, unevenly shaped piece of substance added to liquids to make them boil more calmly. Boiling chips are frequently employed in distillation and heating. When a liquid becomes superheated, a speck of dust or a stirring rod can cause violent flash boiling.Boiling chips provide nucleation sites so the liquid boils smoothly
