Feldspar bụ otu n'ime mineral kachasị mkpa na-akpụ nkume n'ime ala. A na-ejikarị potassium ma ọ bụ sodium nke bara ụba na seramiiki, enamel, iko, abrasives, na ngalaba ụlọ ọrụ mmepụta ihe ndị ọzọ. Potassium feldspar, n'ihi nnukwu ọdịnaya potassium ya na ịbụ ihe na-anaghị agbaze mmiri, enwere ike iji ya n'ọdịnihu maka imepụta fatịlaịza potash, na-eme ka ọ bụrụ ihe dị mkpa maka ịnweta mineral. Feldspar nwere ihe ndị dị ụkọ dịka rubidium na cesium nwere ike ịbụ isi iyi mineral maka iwepụta ihe ndị a. Enwere ike iji feldspar mara mma dị ka nkume ịchọ mma na nkume dị oke ọnụ ahịa.
E wezụga ịbụ ihe e ji arụ ọrụ maka ụlọ ọrụ iko (ihe dị ka 50-60% nke oriri zuru oke), a na-ejikwa feldspar eme ihe n'ụlọ ọrụ seramiiki (30%), ebe a na-ejikwa ihe ndị ọzọ eme ihe na kemịkalụ, ihe nchacha, fiberglass, elektrọd ịgbado ọkụ, na ụlọ ọrụ ndị ọzọ.
Mgbanwe iko
Feldspar bụ otu n'ime ihe ndị bụ isi mejupụtara ngwakọta iko. N'ihi oke ọdịnaya Al₂O₃ na obere ọdịnaya ígwè, feldspar na-agbaze na obere okpomọkụ ma nwee oke agbaze. A na-ejikarị ya eme ka ọdịnaya alumina dị na ngwakọta iko dịkwuo elu, belata okpomọkụ agbaze, ma mee ka ọdịnaya alkali dịkwuo elu, si otú a na-ebelata oke alkali ejiri. Na mgbakwunye, feldspar na-agbaze nwayọ nwayọ ka ọ bụrụ iko, na-egbochi ịmepụta kristal nke nwere ike imebi ngwaahịa ahụ. Feldspar na-enyekwa aka ịchịkwa viscosity nke iko ahụ. N'ozuzu, a na-eji potassium ma ọ bụ sodium feldspar eme ihe na ngwakọta iko dị iche iche.
Ihe ndị e ji seramiiki mee
Tupu a gbaa ya ọkụ, feldspar na-arụ ọrụ dị ka ihe e ji eme ka ọ dị gịrịgịrị, na-ebelata mkpụkọ nkụ na mgbanwe nke ahụ, na-eme ka arụmọrụ nkụ dịkwuo mma, ma na-ebelata oge nkụ. N'oge a na-agba ya ọkụ, feldspar na-arụ ọrụ dị ka ihe na-agbanwe agbanwe iji belata okpomọkụ ọkụ, na-akwalite agbaze nke quartz na kaolin, ma na-eme ka mullite dị n'oge mmiri mmiri. Iko feldspar nke a na-emepụta n'oge agbaze na-ejupụta mkpụrụ kristal mullite dị n'ahụ, na-eme ka ọ dịkwuo nkọ ma na-ebelata porosity, si otú a na-eme ka ike igwe na ihe onwunwe dielectric ya dịkwuo elu. Na mgbakwunye, nhazi nke iko feldspar na-eme ka ahụ dịkwuo mma. Ọnụọgụ feldspar agbakwunyere na ahụ seramiiki dịgasị iche dịka ihe eji emepụta na ihe achọrọ maka ngwaahịa si dị.

Ihe mejupụtara ihe mkpuchi seramiiki bụ feldspar, quartz, na ụrọ, yana ọdịnaya feldspar sitere na 10-35%. N'ime ụlọ ọrụ seramiiki (ma ahụ ma glaze), a na-ejikarị potassium feldspar eme ihe.
Njirimara Anụ Ahụ na Kemịkalụ
Feldspar bụ mineral dị n'ụwa nke ukwuu, nwere nnukwu potassium a maara dị ka potassium feldspar, nke a na-anọchite anya ya na kemịkalụ dị ka KAlSi₃O₈. Orthoclase, microcline, na sanidine bụ mineral potassium feldspar niile. Feldspar ndị a nwere ezigbo kemịkalụ ma na-eguzogidekarị mmebi acid. Ha nwere ike nke 5.5-6.5, ike ndọda kpọmkwem nke 2.55-2.75 t/m³, na ebe agbaze nke 1185-1490°C. Ihe ndị a na-ejikọkarị gụnyere quartz, muscovite, biotite, beryl, garnet, na obere magnetite, columbite, na tantalite.

A na-ekewa ihe nkwụnye Feldspar n'ụdị abụọ dabere na mmalite ha:
1. **Gneiss ma ọ bụ Migmatitic Gneiss**: Ụfọdụ akwara na-apụta na granite ma ọ bụ nnukwu nkume, ma ọ bụ na mpaghara kọntaktị ha. A na-etinyekarị ọla ahụ n'ime mpaghara ngọngọ feldspar nke pegmatites ma ọ bụ feldspar pegmatites dị iche iche.
2. **Ntinye Feldspar nke Ụdị Nkume Igneous**: Ndekọ ndị a na-apụta n'ime nkume acidic, etiti, na alkaline igneous. Ndị a na-ahụ na nkume alkaline kacha mkpa, dị ka nepheline syenite, nke na-esote granite, albite granite, orthoclase granite, na quartz orthoclase granite deposits.
