Cinder vs. Coal — What’s the Difference?
网页2024年4月2日 · Cinder is a residue of combustion, consisting of ash and small bits of incompletely burned material, while coal is a fossil fuel formed from plant remains, used primarily for generating heat and electricity.
What Is Cinder? - EarthCycle
网页2024年6月7日 · Cinder, also referred to as volcanic cinder, volcanic scoria, or simply scoria, is a type of pyroclastic material produced during volcanic eruptions. It’s a dark, porous, and sometimes glassy substance that forms as gas-rich magma is expelled from a volcano and rapidly cools and solidifies in the air.
Is Natural Cinder a good soil amendment?
网页2020年1月26日 · Coal cinders are mainly oxides of silicon (i.e. sand), aluminium, calcium (i.e. lime), and iron, with vary variable composition depending where the coal was mined. Some can contain as much as 40% lime! There may also be enough contamination from heavy metals to cause groundwater pollution if it is dumped in large quantities.
