Ihe bara nnukwu uru nke okike Odo Garnet gburugburu 3.0mm

Nkọwa ngwaahịa:

Garnet, nke a na-akpọ ziyawu ma ọ bụ ziyawu na China oge ochie, bụ otu mineral ndị e ji mee ihe dị ka nkume dị oké ọnụ ahịa na abrasives n'oge ọla.Garnet nkịtị bụ uhie.Garnet English "garnet" sitere na Latin "granatus" (ọka), nke nwere ike si "Punica granatum" (pomegranate).Ọ bụ osisi nwere mkpụrụ na-acha uhie uhie, na ọdịdị ya, nha ya na agba ya yiri ụfọdụ kristal garnet.
A na-ekewa garnets ndị a na-ahụkarị n'ime ụdị isii dịka ihe mejupụtara kemịkal ha siri dị, ya bụ, pyrope, almandine, spessartite, andradite, Grossular, na variants bụ tsavorite, Hessonite, na uvarovite.Garnet ụdị abụọ siri ike ngwọta usoro: (1) red garnet ígwè aluminum garnet manganese aluminum garnet na;(2) Calcium chromium garnet calcium aluminum garnet calcium iron garnet.Garnet enweghị ọkwa ọkwa n'ụwa.Ndị a na-akpọ "A" bụ ndị a na-ekewa dị ka echiche nke onwe.Otu garnet nwere ike ịkọ ọnụọgụ dị iche iche na aka dị iche iche.[1]

Isi ihe:

Ngwakọta kemịkalụ nke garnet dị mgbagwoju anya, na ihe dị iche iche na-emepụta njikọ dị iche iche, ya mere a na-emepụta usoro ezinụlọ garnet nwere ụdị ọdịdị na ihe oyiyi.N'ozuzu usoro bụ a3b2 (SiO4) 3, ebe a na-anọchi anya divalent ọcha (calcium, magnesium, ígwè, manganese, wdg) na B na-anọchi anya trivalent ọcha (aluminom, ígwè, chromium, titanium, vanadium, zirconium, wdg).Ndị a na-ahụkarị bụ magnesia aluminom garnet, nke nwere chromium na iron ọcha na ọbara ọbara ọbara, ọbara ọbara na-acha odo odo na maroon;Nke abụọ bụ ígwè aluminom garnet, nke na-acha ọbara ọbara na-acha odo odo.kristal nwere mmepe nsonye nwere ike wepụta ìhè kpakpando akụkụ anọ;Magnesium iron garnet bụ ìhè rose-acha odo odo na-acha ọbara ọbara, nke bụ otu n'ime ihe dị mkpa iche nke garnet gemstones;Calcium aluminum garnet nwere trace vanadium na ion chromium, ya mere a na-akpọ ya ụdị akwụkwọ ndụ akwụkwọ ndụ dị elu.
N'ihi radius yiri nke trivalent cations, ngbanwe isomorphic dị mfe ime n'etiti ha.Ụdị cations dị iche iche.N'ihi na CA nwere nnukwu radius karịa mg, Fe na Mn plasma, ọ na-esiri ike iji isomorphism dochie ya.Ya mere, a na-ekekarị garnet ụzọ abụọ:
(1) Usoro aluminom: mg3al2 (SiO4) 3 － fe3al2 (SiO4) 3 － mn3al2 (SiO4) 3
Ọ bụ usoro isomorphic nke nwere divalent cations dị ka Mg, Fe na Mn nwere obere radius na trivalent cations dị ka al.Ụdị ndị a na-emekarị gụnyere magnesium aluminum garnet, ígwè aluminum garnet na manganese aluminum garnet.
(2) Usoro calcium: ca3al2 (SiO4) 3 － Ca3Fe2 (SiO4) 3 － ca3cr2 (SiO4) 3
(3) Ọ bụ usoro isomorphic nke divalent cation CA nwere nnukwu radius na-achị.Ndị nkịtị bụ calcium aluminum garnet, calcium iron garnet na calcium chromium garnet.Na mgbakwunye, a na-ejikọta lattice nke ụfọdụ garnets na ion OH iji mepụta ụdị mmiri mmiri, dị ka mmiri calcium aluminum garnet.N'ihi nnukwu mgbanwe isomorphic, ihe mejupụtara kemịkalụ nke garnet na-adịkarị mgbagwoju anya.Ngwakọta nke garnet na okike na-abụkarị ọnọdụ mgbanwe nke isomorphic nnọchi, yana enwere obere garnets nwere akụkụ ndị otu njedebe.[2]
