Magnezyum’u kim ke\u015ffetti<\/h2>\n

Magnezyum, s\u00fclfat h\u00e2linde ilk olarak 1695 y\u0131l\u0131nda bulunmu\u015ftur. Epsomda bir m\u00e2den suyunun
\nkaynat\u0131lmas\u0131 sonucu bulunan bu tuz, ila\u00e7 olarak uzun y\u0131llar kullan\u0131lm\u0131\u015ft\u0131r, 1808\u2019de Sir H. Davy<\/strong> ilk olarak
\nsaf olmayan magnezyum; 1829\u2019da Antoine Bussy<\/strong> \u00e7ok miktarda saf magnezyum elde etti. Bussy,
\nba\u015flang\u0131\u00e7 maddesi olarak susuz magnezyum klor\u00fcr kulland\u0131. 1852\u2019de erimi\u015f magnezyum klor\u00fcr\u00fcn
\nelektrolizinden saf magnezyum elde edildi. 1866 y\u0131l\u0131nda Almanya\u2019da geli\u015ftirilmi\u015f \u201cBunsen elektrolitik<\/strong>
\n h\u00fccresi<\/strong>\u201d ile ticar\u00ee \u00f6l\u00e7\u00fclerde elde edilmi\u015ftir.<\/p>\n

Tabiatta magnezit minerali h\u00e2linde bulunur ve magnezyum elementi\u00a0\u00fcretiminde kullan\u0131lan en \u00f6nemli cevherdir. Magnezyum karbonat, san\u00e2yide bir\u00e7ok sahada; \u0131s\u0131\u00a0izolasyonunda, g\u0131d\u00e2larda, kozmetiklerde, kau\u00e7uklarda, m\u00fcrekkeplerde ve camda katk\u0131 maddesi olarak\u00a0kullan\u0131l\u0131r. Ayr\u0131ca, trisilikat tuzu gibi magnezyum karbonat da bir antiasittir. M\u00eede-barsak \u00fclserlerinde il\u00e2\u00e7\u00a0olarak faydalan\u0131l\u0131r.<\/p>\n

Magnezyum hafif ve parlak beyaz bir metal olmas\u0131 sebebiyle hafif ala\u015f\u0131mlar\u0131n\u00a0yap\u0131lmas\u0131nda kullan\u0131l\u0131r. Ayr\u0131ca gerekli sertli\u011fi ve sa\u011flaml\u0131\u011f\u0131 ede etmek i\u00e7in birden \u00e7ok metal ile ala\u015f\u0131m\u00a0h\u00e2line getirilir. Bu ala\u015f\u0131mlar\u0131 ticarette toz, levha ve \u015ferit h\u00e2linde sat\u0131l\u0131r.<\/p>\n

Magnezyum Nerelerde Kullan\u0131l\u0131r<\/h2>\n

Magnezyum ve ala\u015f\u0131mlar\u0131 \u00e7e\u015fitli alanlarda kullan\u0131l\u0131r. Mesel\u00e2 1920\u2019den sonra u\u00e7ak yap\u0131m\u0131nda kullan\u0131ld\u0131.
\nMagnezyum ala\u015f\u0131mlar\u0131n\u0131n elektronikte geni\u015f bir kullanma alan\u0131 vard\u0131r. Radar ekranlar\u0131nda, antenlerde,
\nteyp \u015feritlerinde, haf\u0131za disklerinde, telsiz cihazlar\u0131nda ve \u00e7e\u015fitli \u015faselerde kullan\u0131l\u0131r.\u00a0Ta\u015f\u0131mac\u0131l\u0131kta kamyon otob\u00fcs kasalar\u0131nda ve g\u00f6vdelerinde de magnezyum ala\u015f\u0131mlar\u0131 kullan\u0131l\u0131r. Tren\u00a0yolu ta\u015f\u0131mac\u0131l\u0131\u011f\u0131nda pek magnezyum kullan\u0131lmaz. Ancak pulman ve lokanta vagonlar\u0131nda mobilya\u00a0olarak kullan\u0131l\u0131r. Magnezyum, ala\u015f\u0131mlar\u0131n\u0131n mukavemeti d\u00fc\u015f\u00fck oldu\u011fu h\u00e2lde, muk\u00e2vemet\/yo\u011funluk\u00a0de\u011ferinin y\u00fcksek olmas\u0131 sebebiyle tercih edilmektedir. Manyezyum, y\u00fcksek elektropozitif karakteri\u00a0sebebiyle di\u011fer metallerin korunmas\u0131nda anod olarak kullan\u0131l\u0131r.<\/p>\n

\u0130nsan v\u00fccudunda magenzyum<\/h2>\n

Magnezyum v\u00fccutta karbonhidrat ve kalsiyum metabolizmas\u0131nda yer al\u0131r. V\u00fccuttaki\u00a0ma\u011fnezyumun yakla\u015f\u0131k d\u00f6rtte \u00fc\u00e7\u00fc kemiklerde, di\u011fer k\u0131sm\u0131 ise yumu\u015fak dokularda ve v\u00fccut s\u0131v\u0131lar\u0131nda\u00a0bulunur. V\u00fccut s\u0131v\u0131lar\u0131ndaki Mg+2 iyonlar\u0131 g\u0131d\u00e2lar ve ba\u015fka maddelerin h\u00fccre i\u00e7inde par\u00e7alanmas\u0131nda\u00a0rol oynarlar. Ayr\u0131ca kas ve sinirlerin uyar\u0131lmas\u0131nda da fonksiyonlar\u0131 vard\u0131r.\u00a0Magnezyum eksikli\u011finin, kronik b\u00f6brek hastal\u0131klar\u0131na, \u015feker hastal\u0131\u011f\u0131 gibi durumlarda ortaya \u00e7\u0131kan\u00a0asidozlara yol a\u00e7t\u0131\u011f\u0131 belirtilmektedir. Magnezyum ba\u015fl\u0131ca, tah\u0131l ve baklagillerde, kuruyemi\u015flerde, et ve\u00a0s\u00fctte bulunur.<\/p>\n","protected":false},"excerpt":{"rendered":"
