Burnt limes

Maintenance of conditions ia the culture environment that keep stress to a minimum is one of the best methods of a voiding diseases. Vacciaes have beea developed agaiast several diseases and more are under development. Selective breeding of animals with disease resistance has met with only limited success. Good sanitation and disiafection of contaminated faciUties are important avoidance and control measure. Some disiafectants are Hsted ia Table 6. Poad soils can be sterilized with burnt lime (CaO), hydrated lime [Ca(OH)2], or chlorine compounds (12). 

Ground burnt lime refers to ground quicklime used for agricultural liming. 

The chemical formula for limestone is CaCOj and upon burning forms calcium oxide (CaO), which is known as burnt lime. Calcium oxide, when mixed with water, forms calcium hydroxide (Ca(OH)2). Calcium hydroxide is used to treat water as a coagulation aid along with aluminum sulfate.

Historically, military pyrotechnics had rheir origin as incendiaries. The Bible refers to the use of firebrands (Judges 15 4, 5) and to the action of water on naphtha and burnt lime (II Maccabees 20—36) (I Kings 18 31—38). Such self-igniting systems were known as automatic fire (Ref 130, p 5) and culminated in Greek Fire (Vo 7j HI 17). Crucial to the further develop-...

Hahn s Explosive. A cheap explosive mixture prepared as follows Burnt lime was dissolved in raw, odorless nitric-acid so as to produce a clear transparent fluid resembling petroleum jelly. This fluid was diluted with 1 to 5 parts of water according to the desired explosive power, and then mixed with a powdered cellulosic material such as peat, sawdust, etc, until a consistant mass was obtained. After giving this mass any suitable form, it was dried and used as a... 

Calcium oxide is a white caustic crystalline alkali substance that goes by the common name lime. The term lime is used both generically for several calcium compounds and with adjectives to qualify different forms of lime. This entry equates lime, also called quicklime or burnt lime, with the compound calcium oxide. Hydrated lime, made by combining lime with water, is calcium hydroxide and is often referred to as slaked lime (Ca(OH)2). Dolomite limes contain magnesium as well as calcium. Limestone is the compound calcium carbonate. The term lime comes from the Old English word lim for a sticky substance and denotes lime s traditional use to produce mortar. Calx was the Latin word for lime and was used to name the element calcium.
