Qo‘rg‘oshin ishlab chiqarishning qisqacha mazmuni
Mualliflar: Hojiyev Shohruh Toshpo‘latovich, Raxmataliyev Shohruh Ashur o‘g‘li
Qo‘rg‘oshinning xususiyatlari:
Pb – kumushrang oq, og„ir rangli metall bo„lib, zichligi 11,35 g/sm
3
va
bolg„alanuvchan. Suyuqlanish harorati 327
o
C, qaynash harorati esa 1749
o
C,
kristall panjarasi: yoqlari markazlashgan kub shaklida.
Qo„rg„oshin va uning birikmalari juda zaharli.
Dmitriy Mendeleyevning
kimyoviy elementlar davriy jadvalida 82-o„rinda, IV guruhda joylashgan bo„lib,
atom massasi 207,19 ga teng.
Qo‘llanilishi:
Qo„rg„oshinli akkumlyatorlar olishda, lak bo„yoq
moddalar sohasida,
hasharotlarga qarshi dori vositalari,
xrustall shisha tayyorlashda, bosmaxona
muhrlari tayorlashda ishlatiladi.
Bundan tashqari, radiatsion moddalarni saqlash
uchun
kapsulalar tayyorlashda, arzon “Pyuter” qotishmasi (Sn 85-95%, Pb 15-
10%) ni tayyorlashda, elektronikada kovsharlash uchun qotishma (67% Pb va 33%
Sn) hamda podshipniklar olishda qo„llaniladi. Qo„rg„oshin metalini Alkimyogarlar
Saturn sayyorasiga qiyoslashgan.
