WebbThese compounds are in little balls called stars, made of a similar compound to what makes a sparkler work. Different metals burn in different colors. For example, if a copper compound is lit, its flame will be a blue-green color. Calcium burns red-colored and potassium burns purple. In fireworks, metals are combined to create different colors.

Webb23 mars 2024 · Germanium is a chemical element. People sometimes use it as medicine. Despite serious safety concerns, germanium is used for cancer, heart disease, hepatitis, glaucoma, and other conditions. But ... In pyrotechnics, charcoal, iron filings, aluminum, titanium and metal alloys such as magnalium may be used to create sparks. The quantity and style of sparks produced depends on the composition and pyrophoricity of the metal and can be used to identify the type of metal by spark testing. In the case of iron, the presence of carbon is required, as in carbon steel — about 0.7% is best for large sparks. The carbon burns explosively in the hot iron and this produces pretty, branching sparks. … WebbGermanium is more used than silicon for radiation detection because the average energy necessary to create an electron-hole pair is 3.6 eV for silicon and 2.9 eV for germanium, which provides the latter a better resolution in energy. rayman 3 intro
