Red Phosphorus - Structure, Properties, Production, and Uses
网页Red phosphorus is one of the most common allotropes of phosphorus and is considered to be a derivative of the P 4 molecule. It exists in an amorphous (non-crystalline) network of phosphorus atoms. It is found to be more stable than white phosphorus (another naturally occurring phosphorus allotrope).
How to Obtain Red Phosphorus | Sciencing
网页2018年12月15日 · Red phosphorus, a relatively stable allotrope of phosphorus, has many uses. For example, it's a component of fireworks, flares and matches; it's used to dope silicon; and it's a plant fertilizer. You can obtain it by boiling urine with carbon or by reacting bone-ash with sulfuric acid and carbon.
