Kedu ihe a na-eji Amorphous boron, Boron ntụ ntụ na eke boron?

Enwere ngwa ngwa maka Amorphous boron, Boron ntụ ntụ na eke boron. A na-eji ha eme ihe na metallurgy, electronics, medicine, ceramics, nuclear industry, chemical industry and other field.

1. A na-eji boron amorphous eme ihe na ụlọ ọrụ ụgbọ ala dị ka ihe ọkụ ọkụ na airbags na belt tighteners. A na-eji boron amorphous eme ihe na pyrotechnics na rọketi dị ka ihe mgbakwunye na flares, ọkụ na-egbu oge, mmanụ ọkụ siri ike, na ihe mgbawa. Ọ na-enye flares a agba akwụkwọ ndụ akwụkwọ ndụ pụrụ iche.
