marvarid ishlab chiqarish Turmalin minerallarining xususiyatlari qanday?

Joylashtirilgan bilan Kador

(1) Murakkab kompozitsiya: Turmalin juda murakkab boro-alyuminosilikat mineralidir, va u tabiatdagi eng murakkab kimyoviy tarkibga ega marvarid mineralidir. U magniy kabi bir yoki bir nechta elementlarni o'z ichiga olishi mumkin, temir, litiy, kaliy, natriy, va hokazo. Ushbu elementlarning turli xil tarkib nisbatlari tufayli, turmalin ko'pincha turli xil ranglarga ega. Masalan, marganets, u qizil yoki pushti turmalin bo'lishi mumkin, xrom va vanadiy turmalinni zumrad yashil ko'rinishiga olib kelishi mumkin, temir va titan esa turmalinni qora rangga aylantirishi mumkin.

(2) Shakl oddiy: Turmalin trigonal kristalli tizimga tegishli, kristall uzun ustunli yoki igna shaklida, va ustunning ikki uchi ko'pincha turli konuslardir. Kristal tekislikda ko'pincha vertikal chiziqlar mavjud. Kristalning ko'ndalang kesimi teng qirrali uchburchakdir, va uchburchakning har bir tomoni tashqariga chiqadi, shuning uchun aniqlash osonroq.

(3) Ranglarning xilma-xilligi: Turmalin eng rangli toshdir. Rangsiz kabi ranglarga ega bo'lishi mumkin, pushti, qizil, yashil rang, ko'k, sariq, va jigarrang. Ba'zan bir xil kristall bir nechta rangda paydo bo'lishi mumkin, yoki xuddi shu kristalda. Uchlari butunlay boshqacha ranglarga ega, shuning uchun u chaqiriladi "ko'p rangli turmalin".

(4) Boshqa xususiyatlar: qattiqlik 7～7,5, zichligi taxminan 3 g / sm3, qobiq shaklidagi sinish, shisha qopqog'ini, shaffof yoki noaniq, piroelektrik. Gamma nurlari bilan nurlanganidan keyin, turmalin turli xil aralashmalar tufayli turli xil rangga ega bo'lishi mumkin.

Turmalinning rangi uning qiymati bilan chambarchas bog'liq. Masalan, qora yoki rangsiz turmalin zargarlik buyumlarida foydasiz, qizil esa, yashil yoki ko'p rangli turmalin zargarlik sanoati tomonidan qo'yilgan maqsaddir. Umuman, the price of beautiful and transparent tourmaline is slightly higher than that of aquamarine. Masalan, the price of transparent green tourmaline produced in China is about 10,000 yuan per kilogram. Bu "color-changing tourmaline" with obvious discoloration characteristics is very rare and has become the object of collectors' pursuit, and its value is very high without price.

Most tourmaline cat's eyes (cat's eye tourmaline) often have a large package body, which makes the flash wide and scattered, so the value is very low. The price of a small amount of package body is small, so cat's eye is narrow and sharp, egiluvchan, and the price is 15-20 AQSh dollari CARAT, dan ortiq 10 times higher than that of high-quality tourmaline without cat's eye effect.
