Titan bilan taqqoslash
Titanium is not actually a rare substance, as it is the ninth most abundant element and the fourth most abundant structural metal in the Earth's crust, surpassing aluminum, iron, and magnesium. Unfortunately, it is rarely found in high concentrations and never in pure form. Therefore, the difficulty of metal processing makes it expensive. Even today, it's just a mass production process, not a continuous process like other structural metals.
Titanium is commonly found in ilmenite (fatio3) in Russia's Ilmen Mountains or in rutile (tio2) ore found on beaches in Australia, India and Mexico. Titanium dioxide is a versatile white pigment used in paints, paper and plastics that consumes most of the world's production. In addition to Russia, Australia, India and Mexico, viable deposits include deposits in the United States, Canada, South Africa, Sierra Leone, Ukraine, Norway and Malaysia.
Bugungi kunda ma'lum bo'lgan davriy tizimdagi 112 kimyoviy elementning taxminan 85 foizi metallar yoki metallardir. Metalllarni tasniflashning ko'plab usullari mavjud, masalan, qora yoki rangli metallar, quyma yoki sinterlangan metallar, engil metallar yoki og'ir metallar.
Titan rangli metallarga-va yengil metallarga boʻlinadi. Metalllarning xossalari asosan kristall panjaradagi atomlarning metall aloqalariga asoslanadi. Ya'ni, dam olish zonasiga olib boradigan bepul, mobil{1}}baho elektron plaid. Uglerod tolasi bilan mustahkamlangan plastmassalar 300 C dan past haroratlarda titanium qotishmalariga qaraganda yuqori o'ziga xos kuchga ega (1.2-rasm). Yuqori haroratlarda titanium qotishmalarining o'ziga xos kuchi ayniqsa jozibali. Biroq, maksimal harorat uning oksidlanish harakati bilan cheklangan. Titan alyuminiy bu kamchilikni qisman engib o'tganligi sababli, ular qotishma ishlab chiqarishda issiq mavzuga aylandi. An'anaviy yuqori haroratli titan qotishmalari 500C dan oshmasa-da, titan{7}}asosli qotishmalar yuqori haroratli-po'latlar va nikel{9}}asosidagi super qotishmalar bilan bevosita raqobatlashadi.
