Titanyum kimyada sembol\u00fc Ti olan sert, parlak ve g\u00fcm\u00fc\u015f\u00fcms\u00fc bir\u00a0metaldir. 1790 y\u0131l\u0131nda \u0130ngiliz William Gregor <\/strong>taraf\u0131ndan titan\u0131n oksidi ke\u015ffedildi. 1795 y\u0131l\u0131nda Alman\u00a0kimy\u00e2c\u0131s\u0131 Martin H. Klaprotl\u0131<\/strong> ba\u015fka bir maddeden Gregor\u2019un ke\u015ffetti\u011fi maddeyi buldu ve bu oksidin\u00a0metaline titan ismini verdi.<\/p>\n

Minerallerde titan\u0131n muhtelif bile\u015fikleri bulunmaktad\u0131r. Kristal yap\u0131s\u0131 farkl\u0131 olan \u00fc\u00e7 \u00e7e\u015fit titan oksit (TiO2)
\nyerine ge\u00e7ebilen titan minerali vard\u0131r. Rutil ismindeki titan oksit, tetragonal prizmatik; brokit ortorombik;
\nanatas ise tetragonal kristal yap\u0131ya s\u00e2hiptirler.<\/p>\n

Titanyum hemen\u00a0hemen \u00e7elik kadar kuvvetlidir. Fakat yo\u011funlu\u011fu \u00e7eli\u011finkinin yar\u0131s\u0131 kadard\u0131r.

Korozyona dayan\u0131kl\u0131 oldu\u011fundan tatbik alan\u0131 gittik\u00e7e b\u00fcy\u00fcmektedir.<\/p>\n

\u00c7ok pahal\u0131 olan Titanyum, s\u0131n\u0131rl\u0131 olarak asker\u00ee maksatlarla kullan\u0131l\u0131r. Titan hem hafif, hem de
\nmuk\u00e2vim bir metal oldu\u011fu i\u00e7in u\u00e7aklar\u0131n, g\u00fcd\u00fcml\u00fc mermilerin ve toplar\u0131n geri tepme tertibatlar\u0131n\u0131n

\nBu korozyona dayan\u0131kl\u0131 muhtemelen y\u00fczeyde te\u015fekk\u00fcl eden titan dioksidin metali kaplamas\u0131ndand\u0131r.
\nTitan umulmad\u0131k \u015fekilde tuzlu suyun korozyonuna dayan\u0131kl\u0131d\u0131r. Bu y\u00fczden deniz v\u00e2s\u0131talar\u0131n\u0131n suyla

Titanyum, bak\u0131r, \u00e7elik ve al\u00fcminyum gibi metallere kat\u0131l\u0131r. Bu metallerin bir\u00e7ok \u00f6zelliklerine etki etmektedir.\u00a0Mesel\u00e2, paslanmaz \u00e7eli\u011fe il\u00e2ve edilen titan, karbon ve azot muhtev\u00e2s\u0131n\u0131 kararl\u0131 tutar. Titan dioksit\u00a0boya \u00eem\u00e2l\u00e2t\u0131nda pigment olarak, k\u00e2\u011f\u0131t, plastik, cam ve seramik san\u00e2yiinde kullan\u0131l\u0131r. Safir ve yakut
\n\u00eem\u00e2linde de titan dioksitten istif\u00e2de edilir. Titan hidr\u00fcr (TiH2) toz metal\u00fcrjisinde, vakum t\u00fcplerinde
\nhidrojen verici olarak kullan\u0131l\u0131r.<\/p>\n","protected":false},"excerpt":{"rendered":"
