Fosfooraska White, casaan iyo madow - sifooyinka iyo codsiga

Fosfooraska waa element a kiimikada si caddaalad ah wax caadi ah oo ku saabsan dhulkeenna. Its magaca tarjumayaa "iska Ifto Yuuna", sababtoo ah in qaabka saafi ah, u iftiimaa oo dhalaalaysa gudcurka. Fur element this, waxay ahayd arrin by shil, alchemist Henning Brandt, markii uu isku dayay in uu soo saaro dahab ka kaadida. Tan iyo fosfooraska, waa element ugu horeysay ee alchemists ay awoodaan si ay u helaan iyada oo tijaabo ay.

Astaamaha u gaarka ah fosfooraska

Waxaa kiimikaad ahaan waa mid aad u firfircoon, sidaas darteed si dabiici ah waxaa laga heli karaa oo kaliya ee foomka of macdanta - xeryahooda waxyaabaha kale, kuwaas oo ay jiraan 190 nooc oo. The xarunta ugu muhiimsan - phosphate calcium ah (macdanta apatite). Hadda waxaa jira noocyo badan oo ka mid apatite, ugu badan ee kaas oo ah fluorapatite. Of apatite ka kooban yihiin noocyo kala duwan oo dhagax weyn ku aasan - phosphates.

Waayo, noolaha live fosfooraska waa muhiimad weyn, tan iyo qayb ka mid ah borotiinka khudaarta iyo duunyaba foomka xeryahooda kala duwan.

In dhirta, element this waxaa ku jira inta badan borotiinada in abuur iyo in xayawaanka - in borotiinka dhiigga oo kala duwan, caanaha, unugyada maskaxda iyo unugyada neerfaha. qadar badan oo ah fosfooraska ku jira foomka of phosphate calcium in lafihii vertebrates.

Fosfooraska jira saddex hab doorinta allotropic: fosfooraska caddaan, casaan iyo madow. Aynu fiiriyaa si faahfaahsan.

fosfooraska White waxaa laga heli karaa si degdeg ah u qaboojiso uumi. Markaas crystalline sameeyay adag, kaas oo gabi ahaanba waa hufan iyo midab ee gobolka saafi ah. fosfooraska White, loogu tala galay for sale, waxaa sida caadiga ah rinji midabka wax yar ka hurdi iyo muuqaalkiisa waa mid aad la mid ah wax. In walax this qabow waxa uu noqonayaa mid jilicsan, iyo heerkul ka sarreeya 15 degrees noqdo jilicsan iyo si fudud loo jari karaa mindi.

In biyaha, fosfooraska cad aan loo kala diri, laakiin jawaabayaa si fiican ay u qase organic. In hawada waxaa si dhakhso ah oxidizes (bilaabo inuu gubi) oo weli glows mugdi ah. Dhab ahaantii, fikradda ah sheekooyinka maalka iyo Baare iska Ifto Yuuna ah Hound of Baskervilles ku xiran fosfooraska cad. Waa sun awood in halis ah xitaa in yar ka qaataan.

fosfooraska Red - midabka adag oo mugdi ah cas, taas oo wuxuu leeyahay sifooyin aad u kala duwan ka kor lagu sharaxay. Waxaa la oxidized hawada aad u tartiib ah, mugdi ah, shiday, shiday oo keliya by kuleylinta ah xal dareeraha organic waa wax aan macquul aheyn, oo ma aha sun ah. kulaylinta A xoog leh, at taas oo ay jirto ma helaan hawada, waxa aan xaabo, waxaa beddelay uumi, taas oo, on qaboojinta, iyo fosfooraska ka helay cad. In sari ee labada xubno ka sameeyay xabagta fosfooraska, taas oo daliil u joogitaanka in ay qaab-dhismeedka of element isku. In si kale loo dhigo, waxay la aasaasay by a element hal - phosphor - iyo waa hab doorinta ay allotropic.

fosfooraska Black waa la diyaariyey ka cad at 200 degrees Celsius cadaadis sare. Waxay leedahay qaab oo israac raacsan, luster macdan ah iyo muuqaalka la mid ah graphite. Dhammaan noocyada kala duwan ee walax adag ay kacsan tahay ugu yaraan.

Isticmaalka fosfooraska

wax soo saarka Modern of fosfooraska - oo ku saabsan mid ka mid million tons sannadkii. saarayaasha Major: Maraykanka, Holland, Canada, Germany.

bulk of isticmaalka saaray fosfooraska, waayo, kaamerada acid phosphoric waxaa loo isticmaalaa wax soo saarka ee Bacriminta iyo phosphates. fosfooraska White waxaa loo isticmaalaa sida wakiilka ah hawadda iyo qiiq soo saara, oo ay ku jiraan for rasaas lagula soconayo.

Red loo isticmaalo soo saaridda ee dusha ah hawadda ee dhiibsan, iyo in wax soo saarka ee nalalka incandescent iftiinka, uu u dhaqmo sida getter ah.

Fosfooraska ayaa helay codsiga in metallurgy. Waxa loo isticmaalaa sida daro ah in ay soo saaraan Alloys doped, solders, Alloys magnetic jilicsan iyo antifriction.
