Mi az a magf\u00fazi\u00f3?<\/h2>\n\n\n\n

A magf\u00fazi\u00f3 egyfajta nukle\u00e1ris folyamat, amely akkor k\u00f6vetkezik be, amikor k\u00e9t vagy t\u00f6bb atommag egyes\u00fcl, hogy egyetlen, nagyobb atommagot hozzon l\u00e9tre. <\/p>\n\n\n\n

A f\u00fazi\u00f3s reakci\u00f3k az anyag plazma nev\u0171 \u00e1llapot\u00e1ban j\u00e1tsz\u00f3dnak le, amely egy forr\u00f3, t\u00f6lt\u00f6tt g\u00e1z, amely pozit\u00edv ionokb\u00f3l \u00e9s szabadon mozg\u00f3 elektronokb\u00f3l \u00e1ll, \u00e9s a szil\u00e1rd anyagokt\u00f3l, folyad\u00e9kokt\u00f3l vagy g\u00e1zokt\u00f3l elt\u00e9r\u0151 tulajdons\u00e1gokkal rendelkezik. <\/p>\n\n\n\n

\u00d6sszefoglalva, a magf\u00fazi\u00f3 az a mechanizmus, amelyen kereszt\u00fcl a A Nap \u00e9s m\u00e1s csillagok energi\u00e1t nyernek<\/strong>.<\/p>\n\n\n\n

P\u00e9ld\u00e1ul: A tr\u00edcium- \u00e9s deut\u00e9riumatomok (hidrog\u00e9n-3 \u00e9s hidrog\u00e9n-2 hidrog\u00e9nizot\u00f3pok) egyes\u00fclve neutront \u00e9s h\u00e9liumizot\u00f3pot hoznak l\u00e9tre. Ezzel egy\u00fctt hatalmas mennyis\u00e9g\u0171 energia szabadul fel.<\/p>\n\n\n\n

Ez az energia felhaszn\u00e1lhat\u00f3 elektromos \u00e1ram el\u0151\u00e1ll\u00edt\u00e1s\u00e1ra vagy m\u00e1s dolgok m\u0171k\u00f6dtet\u00e9s\u00e9re. \u00dagy gondolj\u00e1k, hogy ez egy potenci\u00e1lisan v\u00e9gtelen \u00e9s tiszta energiaforr\u00e1s. <\/p>\n\n\n\n

A magas h\u0151m\u00e9rs\u00e9klet miatt elegend\u0151 energi\u00e1val rendelkeznek ahhoz, hogy legy\u0151zz\u00e9k egym\u00e1s elektromos ellen\u00e1ll\u00e1s\u00e1t.

Magf\u00fazi\u00f3 vs. maghasad\u00e1s<\/h2>\n\n\n\n

Mind a maghasad\u00e1s, mind a f\u00fazi\u00f3 olyan nukle\u00e1ris reakci\u00f3k, amelyek az atomok elmozdul\u00e1s\u00e1val energi\u00e1t termelnek, de mi a k\u00fcl\u00f6nbs\u00e9g a kett\u0151 k\u00f6z\u00f6tt? <\/p>\n\n\n\n

Albert Einstein j\u00f3slata, miszerint a t\u00f6meg energi\u00e1v\u00e1 alak\u00edthat\u00f3, inspir\u00e1lta az atommaghasad\u00e1s felfedez\u00e9s\u00e9t. A tud\u00f3sok 1939-ben kezdtek k\u00eds\u00e9rletezni, Enrico Fermi pedig egy \u00e9vvel k\u00e9s\u0151bb meg\u00e9p\u00edtette az els\u0151 atomreaktort.<\/p>\n\n\n\n

Az atommaghasad\u00e1s nagy mennyis\u00e9g\u0171 radioakt\u00edv hullad\u00e9kot termel, amely vesz\u00e9lyes lehet, \u00e9s amelyet gondosan kell t\u00e1rolni - ak\u00e1r t\u00f6bb sz\u00e1z \u00e9vig is.

\u00c9rdemes felh\u00edvni a figyelmet arra is, hogy a maghasad\u00e1s nem term\u00e9szetes folyamat, \u00e9s el\u0151 kell id\u00e9zni, m\u00edg a magf\u00fazi\u00f3 term\u00e9szetes folyamat, p\u00e9ld\u00e1ul a Nap a magf\u00fazi\u00f3 r\u00e9v\u00e9n termel energi\u00e1t.<\/p>\n\n\n\n

Mi\u00e9rt fontos a magf\u00fazi\u00f3?<\/h2>\n\n\n\n

A f\u00fazi\u00f3s reaktorok minim\u00e1lis \u00fcvegh\u00e1zhat\u00e1s\u00fa g\u00e1zkibocs\u00e1t\u00e1s, radioakt\u00edv hullad\u00e9k vagy egy\u00e9b k\u00f6rnyezeti k\u00f6vetkezm\u00e9nyek n\u00e9lk\u00fcl k\u00e9pesek energi\u00e1t termelni.
