Kedu ihe bụ Boron ntụ ntụ maka?
A na-eji ntụ ntụ Boron eme ihe na metallurgy, electronics, medicine, ceramics, nuclear industry, chemical industry and other field.
1. Boron ntụ ntụ bụ ụdị mmanụ ígwè nke nwere nnukwu gravimetric na volumetric calorific values, nke ejirila mee ihe n'ebe ndị agha dị ka ndị na-emepụta ihe siri ike, ihe mgbawa dị elu, na pyrotechnics. Na ọkụ ọkụ nke boron ntụ ntụ na-ebelata nke ukwuu n'ihi ọdịdị ya na-adịghị mma na nnukwu ebe dị elu;
2. A na-eji ntụ ntụ boron mee ihe dị ka ihe na-emepụta ihe na-emepụta ihe na-emepụta ihe na-emepụta ihe na-emepụta ihe na-emepụta ihe na-emepụta ihe na-arụ ọrụ nke ígwè. A pụkwara iji ya kpuchie wires tungsten ma ọ bụ dị ka ihe njupụta na ihe ndị nwere ọla ma ọ bụ ceramik. A na-ejikarị boron mee ihe n'ụdị alloys dị iche iche iji mee ka ọla ndị ọzọ sie ike, kpọmkwem ihe mkpuchi brazing na-ekpo ọkụ.
3. A na-eji ntụ ntụ boron mee ihe dị ka deoxidizer na-agbaze ọla kọpa na-enweghị oxygen. A na-agbakwunye obere ntụ ntụ boron n'oge usoro mgbaze ígwè. N'otu aka ahụ, a na-eji ya dị ka deoxidizer iji gbochie ígwè ahụ ka ọ ghara ịdị na-ekpo ọkụ na okpomọkụ dị elu. A na-eji ntụ ntụ boron mee ihe dị ka ihe mgbakwunye maka brik magnesia-carbon nke a na-eji na ọkụ ọkụ dị elu maka ịmepụta ígwè;
4. Boron ntụ ntụ na-abakwa uru na ngwa ọ bụla ebe a na-achọ ebe dị elu dị ka ọgwụgwọ mmiri na mmanụ ọkụ na ngwa anyanwụ. Nanoparticles na-emepụtakwa ebe dị elu nke ukwuu.
5. Boron ntụ ntụ bụkwa ihe dị mkpa maka ịmepụta boron halide dị ọcha, na ihe ndị ọzọ boron compound; A pụkwara iji ntụ ntụ boron mee ihe dị ka enyemaka ịgbado ọkụ; A na-eji ntụ ntụ Boron mee ihe dị ka onye mmalite maka ikuku ikuku ụgbọ ala;
