Garnet

Garnets yog ib pawg ntawm silicate minerals. Peb siv nws txij thaum lub hnub nyoog Bronze li gemstones thiab abrasives.

Whereas nyob rau hauv daim ntawv cog lus hauv B hauv qhov chaw kawm B pom cov kev hloov pauv hloov ntawm uvarovite thiab andradite, tiam sis tsuas yog siv cov khoom sib xyaw ntawm cov thiab grossular nkaus xwb. Qhov no tshwm sim vim hais tias cov ionic radii ntawm Cr3 thiab Fe3 zoo sib xws thiab yog cov loj dua li ntawm Al3.
