配方问题好像确实影响到不同战场的希腊火性质。海军的似乎稀一些,陆军的似乎固体化?以便于使用,当然,这都是我个人的猜测`
以前买过一套《世界通史》,上面有一幅据说是拜占庭用希腊火攻击敌人舰队的画。
The ingredients, process of manufacture, and usage were a very carefully guarded military secret -- so secret it remains a source of speculation to this day. Speculations include:
naphtha, niter, sulfur[citation needed]
petroleum, quicklime, sulfur[citation needed]
phosphorus and saltpeter[citation needed]
It is not clear if it was ignited by a flame as the mixture emerged from the syringe, or if it ignited spontaneously when it came into contact with water. If the latter is the case, it is possible that the active ingredient was calcium phosphide, made by heating lime, bones, and charcoal. On contact with water, calcium phosphide releases phosphine, which ignites spontaneously. The reaction of quicklime with water also creates enough heat to ignite hydrocarbons, especially if an oxidizer such as saltpeter is present. However, Greek fire was also used on land.
These ingredients were apparently heated in a cauldron, and then pumped out through a siphon or large syringe (known as a siphonarios) mounted on the bow of the ship. Such ship was herself called siphonophoros. It could also be used in hand grenades, made of earthenware vessels. If a pyrophoric reaction was involved, perhaps these grenades contained chambers for the fluids, which mixed and ignited when the vessel broke on impact with the target. |
