Ferroboron (CAS Registry Number 11108–67-1) is a ferroalloy of iron and boron with boron content between 17.5 and 20%. [1] It is manufactured either by carbothermic reduction of boric acid in an electric arc furnace together with carbon steel, or by the aluminothermic reduction of boric acid in the presence of iron. [1]
The introduction of boron steel elements introduced issues for accident scene rescuers as its high strength and hardness resisted many conventional cutting tools (hydraulic rescue tools) in use at that time. [3] [4] Flat boron steel for automotive use is hot stamped in cooled molds from the austentic state (obtained by heating to 900-950 °C ...
Iron borides can be formed by thermochemically reacting boron rich compounds on an iron surface to form a mixture of iron borides, in a process known as boriding.There are a number of ways of forming boride coatings, including gas boriding, molten salt boriding, and pack boriding. [6]

Excess boron is toxic to plants so care must be taken to ensure correct application rate and even coverage. [7] While boron may be sprayed on leaves, excess will cause plant damage. Application of boron may not correct boron deficiency in alkaline soils because even with the addition of boron, it may remain unavailable for plant absorption.
Culinary: used as a nutritionally minor flavoring component in foods or beverages Tea: brewed in hot water to make a beverage (for primarily culinary rather than medicinal or ritual purposes) Medicinal: used, either directly or as a simple extract such as a tea, to cause some physiological effect, usually to treat some ailment or disease
The saj (ṣāğ), though also used in baking, is unlike the clay oven. It is rather a convex griddle made of metal, on which is spread a thin, unleavened dough. Dalman describes it in 1935 as being used by Bedouins from Syria all the way to Arabia, because it can be transported, unlike the tābūn and tannūr. [35]
The plant is composed of thick succulent roots with no stems and the flower develops on surfaces of the host's roots. The flower is used as a temporary trap in order to facilitate pollination. [9] H. africana has an enzyme which allows it to dissolve some of the roots of its host plants in order to attach to them.
