Chinese high yield huge element boron Business Articles | September 18 Jace Sternberger Game Jersey , 2012 The lake in?Tibet,?China, contains many of borax and boric acid. Borax is the most important compounds of boron. In the weld metal, it will be with borax to clean the metal surface.?
Boric acid is also commonly used as a disinfectant in hospitals. Borax in ancient times have already known for the Arab alchemists, they get borax from Tibet, China. Boron is a rare earth elements in other countries. However, in China, there is a wealth of borax ore Elgton Jenkins Game Jersey , boron in China is not a rare element, but a high yield elements!
Although borax marked dealings has a long history, however, the pure, free form boron, until 1808 made by the United Kingdom of David France Gailvsake and Taina. Pure boron is a dark brown, rust-like boron powder, together with aluminum to heat and melt Darnell Savage Jr. Game Jersey , after cooling, can be obtained chunks of crystalline boron. Boron crystal is very hard, the same as diamond, and they are heat-resistant, the melting point of 2075 ° C, it was used in the mechanical industry instead of expensive diamond manufacturing cutting tools and drill. Now, it is heated with a platinum wire is energized Boron tribromide vapor, at 1500 the boron tribromide decomposition and get pure boron.
The use of free state boron is not too large. In industry Rashan Gary Game Jersey , added the millionth of boron to the aluminum, copper, nickel and other metals, can improve the mechanical properties of these metals. The uses of borax is much broader than the free state of the boron, in industry it use to make porcelain, especially fusible glaze enamel. The borax also been used to manufacture a variety of heat-resistant glass and a filler as soap.
In the point of chemical, borax has a special purpose: use a small circle made of platinum wire, dipped in a little borax and put the heating on gas or alcohol lamp. At the beginning Jaire Alexander Game Jersey , borax will emerge in a number of small bubbles crystal water - heat evaporation, and then melt into a colorless liquid. After cooling, became a colorless transparent solid, like a glass bead-like, firmly stick the small circle which made of platinum wire. If you are then dipped in a little metal oxide platinum wire on the lights on the heat, cold, beads been significant on a variety of colors. E.g. dipped metallic cobalt oxide, the beads were blue; dip of chromium oxide green beads; dipped iron oxide Aaron Rodgers Game Jersey , as a yellow beads (heat as a brown). In analytical chemistry, it is called borate beads reaction. Use different colors of boric acid beads, can analysis of various metals. Now, metal powder supplier commonly use boric acid beads reaction to analysis of the metallic minerals collected in the wild, because this method of chemical analysis is very simple, you can quickly determine the chemical composition of the sample. Likewise, borax is often used as a rust remover. Because when borax heated, melting the metal oxides on the surface - rust. In addition Za'Darius Smith Limited Jersey , also used in fireworks borax, because when it is heated, it can radiate beautiful green light.
What worth mentioning is that the borax gradually became a important role in agriculture - Boron. It has been found that the boron content in the plants is not much, and only one hundred thousandth of the dry weight of plants to about one ten thousandth;, however, it is indispensable. If the soil lack of boron, flax, hemp and alfalfa plants will stop growing Billy Turner Limited Jersey , and even death. Sunflower lack of boron, will show up shriveled grain, oil content decreased. If the beet lack of boron will have dry rot - the underground stem rot away; lack of boron legume nodule development will also be affected. According to the study, boron is one of the essential trace element in plant growth, plays a very important role in regulating carbohydrate metabolism of its plants. Apply the right amount into the fields to meet the needs of the crops of boron. But boron application rate must be appropriate, not the more the better; if use too much, the crops will be spared death, even the sheep ate such crops leaves will get the enteritis Adrian Amos Limited Jersey , such enteritis in veterinary medicine known as boron enteritis.
Are you currently somebody who moved directly from high school to doing work daily?
