Makristasi amchere mawonekedwe ambiri maonekedwe osiyanasiyana ndi makulidwe. A mchere amapangidwa ndi maatomu ndi mamolekyu. Pamene maatomu ndi mamolekyu aphatikizana, amapanga dongosolo linalake. Chomaliza mawonekedwe cha mchere kunyezimiritsa atomiki yapachiyambi mawonekedwe.

Poganizira izi, kodi makristasi amasiyana bwanji mumchere?

Za a mchere kupanga a kristalo, imafunika malo kuti ikule. Ndi malo okwanira, makhiristo kulani m’magulu kuti mupange zazikulu kristalo zomangamanga. Koma si onse makhiristo kukhala ndi chitsanzo chomwecho cha malo athyathyathya. Ena makhiristo kukhala ndi mawonekedwe a cubes.

Komanso Dziwani, mawonekedwe a mineral crystal ndi chiyani? Mwachidule, chizolowezi, kapena chowoneka mawonekedwe mwa a kristalo, ndi katundu wakuthupi yemwe angagwiritsidwe ntchito kuthandizira kuzindikira mchere. Ena makhiristo ndi euhedral monga iwo ali wokhazikika, polygonal kapangidwe. Zizolowezi za Euhedral zimaphatikizapo octahedral, monga diamondi, dodecahedral, monga garnets, ndi cubic, monga halite ndi galena.

Komanso, kodi makhiristo opangidwa ndi mchere wosiyanasiyana ndi ofanana?

Kunena mwachidule, a kristalo ndi dongosolo lopangidwa ndi zinthu zosiyanasiyana zachilengedwe pomwe a mchere ndi zinthu mwazokha. Awiri kapena kuposerapo mchere akhoza kukhala ndi yemweyo mankhwala koma amasiyana kwambiri zikafika kristalo kapangidwe. Izi zimadziwika kuti polymorphs.

Kodi makristalo amabwera ndi mawonekedwe otani?

Amakhulupirira kuti alipo asanu ndi awiri mawonekedwe, kapena "kachitidwe" momwe makhiristo akhoza mawonekedwe. Amaphatikizapo cubic, hexagonal, tetragonal, orthorhombic, monoclinic, ndi triclinic.
