calcium phosphide造句

• Other pesticides similar to aluminium phosphide are zinc phosphide and calcium phosphide.
• On contact with water, calcium phosphide releases phosphine, which ignites spontaneously.
• Calcium phosphide and sodium azide were determined to be too difficult to procure.
• Calcium phosphide and zinc phosphide are similar poisons.
• Calcium phosphide is a common impurity in calcium carbide, which may cause the resulting phosphine-contaminated acetylene to ignite spontaneously.
• Calcium phosphide is also used in fireworks, torpedoes, self-igniting naval pyrotechnic flares, and various water-activated ammunition.
• Another similar proposition suggested that Kallinikos had in fact discovered calcium phosphide, which can be made by boiling bones in urine within a sealed vessel.
• During the 1920s and 1930s, Charles Kingsford Smith used separate buoyant canisters of calcium carbide and calcium phosphide as naval flares lasting up to ten minutes.
• They also included a small quantity of calcium phosphide, which in contact with water produced impure phosphine, it spontaneously ignited, thereby igniting the acetylene.
• It remains a matter of speculation and debate, with various proposals including combinations of pine resin, naphtha, quicklime, calcium phosphide, sulfur, or niter.
• Calcium phosphide ( nominally Ca 3 P 2 ) produces more P 2 H 4 than other phosphides because of the preponderance of P-P bonds in the starting material.
• :Try calcium phosphide, it isn't so much a poison really, but it works, unless the calcium phosphide is past it's best before date.
• :Try calcium phosphide, it isn't so much a poison really, but it works, unless the calcium phosphide is past it's best before date.
• Calcium carbide, together with calcium phosphide, is used in floating, self-igniting naval signal flares, such as those produced by the Holmes'Marine Life Protection Association.
• It is speculated that calcium phosphide & mdash; made by boiling bones in urine, within a closed vessel & mdash; was an ingredient of some ancient Greek fire formulas.
• Calcium phosphide is often used in naval flares, as in contact with water it liberates phosphine which self ignites in contact with air; it is often used together with calcium carbide which releases acetylene.
• "' Calcium monophosphide "'is the inorganic compound with the formula CaP . The term " calcium phosphide " also describes the composition Ca 3 P 2, which is also called calcium phosphide.
• "' Calcium monophosphide "'is the inorganic compound with the formula CaP . The term " calcium phosphide " also describes the composition Ca 3 P 2, which is also called calcium phosphide.
• In 1844, Paul Th閚ard, son of the French chemist Louis Jacques Th閚ard, used a cold trap to separate diphosphine from phosphine that had been generated from calcium phosphide, thereby demonstrating that P 2 H 4 is responsible for spontaneous flammability associated with PH 3, and also for the characteristic orange / brown color that can form on surfaces, which is a polymerisation product.
• The pure material is colorless, however pieces of technical-grade calcium carbide are grey or brown and consist of about 80 85 % of CaC 2 ( the rest is CaO ( calcium oxide ), Ca 3 P 2 ( calcium phosphide ), CaS ( calcium sulfide ), Ca 3 N 2 ( calcium nitride ), SiC ( silicon carbide ), etc . ).
