\u00c7inko (Lat. Zinkum, \u0130ng. Zinc, Alm. Zink), mavimsi a\u00e7\u0131k gri renkte, k\u0131r\u0131lgan bir metal. Elementlerin periyodik tablosunda ge\u00e7i\u015f elementleri grubunda yer al\u0131r. D\u00fc\u015f\u00fck kaynama s\u0131cakl\u0131\u011f\u0131 dikkat \u00e7ekicidir. Bu de\u011fer \u00f6zellikle pirometalurjik metal \u00fcretiminde \u00e7ok belirleyici bir etmendir. D\u00f6k\u00fclm\u00fc\u015f halde sert ve k\u0131r\u0131lgand\u0131r. 120\u00b0C’de \u015fekillendirilebilir. Elektrokimyasal potansiyel dizisinde demirden daha negatif de\u011ferdedir. B\u00f6ylece \u00e7inko anot olarak katodik korozyon korumada \u00f6nemli bir kullan\u0131m bulur. Galvanizleme bu t\u00fcr uygulamalardan biridir.<\/p>\n

\u00c7inko, bile\u015fiklerinde (2+) de\u011ferlikli olarak bulunur. Olu\u015fturdu\u011fu bile\u015fiklerde kovalent ba\u011f yapar. Amonyak, amin, siyan\u00fcr ve halojen iyonlar\u0131 ile kompleks bile\u015fikler meydana getirir. Mineral asitlerinde H2 \u00e7\u0131k\u0131\u015f\u0131yla \u00e7\u00f6z\u00fcn\u00fcr. Ancak nitrik asitte NOx \u00e7\u0131k\u0131\u015f\u0131 olur. Dolay\u0131s\u0131yla \u00e7inko, \u00f6zellikle toz halde \u00e7ok etkili bir red\u00fckleyicidir. Normal s\u0131cakl\u0131kta havada b\u0131rak\u0131lan metalin y\u00fczeyinde koruyucu bir tabaka olu\u015ftu\u011fundan bu s\u0131cakl\u0131kta halojenlere bile dayan\u0131kl\u0131d\u0131r. HCl gaz\u0131 \u00e7inkoyu \u00e7ok \u00e7abuk korozyona u\u011frat\u0131r. Toz \u00e7inkonun reaksiyona girme kabiliyeti olduk\u00e7a fazla ise de yan\u0131c\u0131 de\u011fildir. Y\u00fcksek s\u0131cakl\u0131kta oksijen, klor ve k\u00fck\u00fcrt gibi elementlerle \u015fiddetle reaksiyona girer. Civa ile sert bir amalgam meydana getirir. Klor\u00fcr ve s\u00fclfat tuzlar\u0131 suda y\u00fcksek miktarda \u00e7\u00f6z\u00fcn\u00fcr. Buna kar\u015f\u0131l\u0131k \u00e7inko oksit, silikat, fosfat ve organik kompleksleri ya suda hi\u00e7 \u00e7\u00f6z\u00fcnmezler ya da \u00e7ok a\u011f\u0131r \u00e7\u00f6z\u00fcn\u00fcrler. Bile\u015fikleri aras\u0131nda \u00e7inko oksitin teknik ve ekonomik de\u011feri vard\u0131r. Organik bile\u015fikleri aras\u0131nda \u00e7inko sabunu en \u00f6nemli kullan\u0131ma sahiptir.<\/p>\n

Nihayet \u00e7inko metali, bu temiz \u00e7\u00f6zeltiden elektroliz yoluyla katot levhalar halinde kazan\u0131l\u0131r. \u00c7inko katotlar ya do\u011frudan d\u00f6k\u00fcmhaneye g\u00f6nderilerek ingotlar halinde d\u00f6k\u00fcl\u00fcr ya da al\u00fcminyum ile ala\u015f\u0131mland\u0131r\u0131l\u0131r.<\/p>\n
Bir di\u011fer \u00e7inko \u00fcretim prosesi de pirometalurjik bir proses olan fla\u015f ergitme y\u00f6ntemidir, ancak bu y\u00f6ntemle elde edilen \u00e7inko oksit, hidrometalurjik alternatifine g\u00f6re daha d\u00fc\u015f\u00fck safiyette \u00e7inko \u00fcretimine yol a\u00e7ar.<\/p>\n
