Elektronik cihazlar\u0131n minyat\u00fcrle\u015ftirilmesi ve entegrasyonu, polimer bazl\u0131 termal y\u00f6netim malzemeleri i\u00e7in daha y\u00fcksek \u0131s\u0131 da\u011f\u0131l\u0131m\u0131 gereksinimlerini ortaya koymu\u015ftur.

Termal plazma teknolojisi, y\u00fcksek s\u0131cakl\u0131\u011f\u0131, kontrol edilebilir reaksiyon atmosferi, y\u00fcksek enerji yo\u011funlu\u011fu ve d\u00fc\u015f\u00fck kirlili\u011fi nedeniyle k\u00fcresel silikon tozu ve al\u00fcmina tozu gibi nano ve mikron \u015fekilli k\u00fcresel tozlar\u0131n haz\u0131rlanmas\u0131nda b\u00fcy\u00fck avantajlara sahiptir.<\/p>\n

Termal plazma teknolojisi<\/p>\n

Plazma, kat\u0131, s\u0131v\u0131 ve gaza ek olarak maddenin d\u00f6rd\u00fcnc\u00fc halidir. Elektronlardan, katyonlardan ve n\u00f6tr par\u00e7ac\u0131klardan olu\u015fan genel olarak elektriksel olarak n\u00f6tr bir agregad\u0131r. Plazmadaki a\u011f\u0131r par\u00e7ac\u0131klar\u0131n s\u0131cakl\u0131\u011f\u0131na g\u00f6re plazma iki kategoriye ayr\u0131labilir: s\u0131cak plazma ve so\u011fuk plazma.<\/p>\n

S\u0131cak plazmadaki a\u011f\u0131r iyonlar\u0131n s\u0131cakl\u0131\u011f\u0131 3\u00d7103 ila 3\u00d7104K’ye ula\u015fabilir ve bu temelde yerel termodinamik denge durumuna ula\u015f\u0131r. Bu durumda, termal plazman\u0131n \u015fu ili\u015fkisi vard\u0131r: elektron s\u0131cakl\u0131\u011f\u0131 Te = plazma s\u0131cakl\u0131\u011f\u0131 Th = uyar\u0131lma s\u0131cakl\u0131\u011f\u0131 Tex = iyonla\u015fma reaksiyon s\u0131cakl\u0131\u011f\u0131 Treac, bu nedenle termal plazman\u0131n d\u00fczg\u00fcn bir termodinamik s\u0131cakl\u0131\u011f\u0131 vard\u0131r.<\/p>\n

K\u00fcresel tozlar\u0131n plazma haz\u0131rlanmas\u0131<\/p>\n

Y\u00fcksek frekansl\u0131 termal plazman\u0131n y\u00fcksek s\u0131cakl\u0131k ve h\u0131zl\u0131 so\u011futma h\u0131z\u0131 \u00f6zelliklerine dayanarak, nanotozlar haz\u0131rlamak i\u00e7in fiziksel buhar biriktirme teknolojisi kullan\u0131l\u0131r.<\/p>\n

Plazma ile k\u00fcresel tozlar\u0131 haz\u0131rlaman\u0131n iki ana yolu vard\u0131r.<\/p>\n

Birincisi, d\u00fczensiz \u015fekilli ve b\u00fcy\u00fck boyutlu ham madde tozlar\u0131n\u0131 termal plazman\u0131n y\u00fcksek s\u0131cakl\u0131k ark\u0131na ge\u00e7irmek ve termal plazman\u0131n \u00fcretti\u011fi y\u00fcksek s\u0131cakl\u0131k ortam\u0131n\u0131 ham madde par\u00e7ac\u0131klar\u0131n\u0131 h\u0131zla \u0131s\u0131tmak ve eritmek (veya y\u00fczeyi eritmek) i\u00e7in kullanmakt\u0131r. Y\u00fczey gerilimi nedeniyle, erimi\u015f toz bir k\u00fcre olu\u015fturur ve k\u00fcresel bir toz elde etmek i\u00e7in uygun bir so\u011futma h\u0131z\u0131nda kat\u0131la\u015f\u0131r. \u0130kincisi, d\u00fczensiz tozlar\u0131 veya \u00f6nc\u00fclleri ham madde ve termal plazmay\u0131 y\u00fcksek s\u0131cakl\u0131kl\u0131 bir \u0131s\u0131 kayna\u011f\u0131 olarak kullanmakt\u0131r. Ham maddeler, i\u00e7indeki aktif par\u00e7ac\u0131klarla reaksiyona girer ve h\u0131zla so\u011futulur ve biriktirilerek ideal toz malzemeler \u00fcretilir.<\/p>\n

Y\u00fcksek s\u0131cakl\u0131k, y\u00fcksek enerji, kontrol edilebilir atmosfer ve termal plazma kirlili\u011fi olmamas\u0131 \u00f6zelliklerinden yararlan\u0131larak, besleme, so\u011futma h\u0131z\u0131 ve plazma g\u00fcc\u00fc gibi haz\u0131rlama s\u00fcrecindeki parametreler kontrol edilerek y\u00fcksek safl\u0131kta, y\u00fcksek k\u00fcresellikte ve farkl\u0131 boyutlarda k\u00fcresel tozlar haz\u0131rlanabilir. Bu nedenle, k\u00fcresel tozlar\u0131 haz\u0131rlamak i\u00e7in plazma teknolojisinin kullan\u0131m\u0131 enerji, havac\u0131l\u0131k, kimya end\u00fcstrisi ve di\u011fer alanlarda giderek daha yayg\u0131n bir \u015fekilde kullan\u0131lmaktad\u0131r.<\/p>\n","protected":false},"excerpt":{"rendered":"
