Boron chinhu chinonzi metalloid, chine maviri allotropes, amorphous boron uye crystalline boron. Amorphous boron ihupfu hwebrown ukuwo crystalline boron iri sirivheri kuita nhema. Crystalline boron granules uye zvimedu zveboron zvakakwirira kuchena boron, zvakanyanya kuoma, uye hazvina kunaka conductor pakamuri tembiricha.
Crystalline Boron
Iyo yekristaro fomu yecrystalline boron inonyanya kuve β-fomu, iyo inogadzirwa kubva ku β-fomu uye γ-fomu kuita cube kuti igadzire yakagadziriswa crystal chimiro. Sekristalline boron inowanzoitika, kuwanda kwayo kunopfuura 80%.Ruvara kazhinji igrey-brown poda kana shava isina kuumbwa zvimedu. Iyo yakajairika particle size yecrystalline boron poda yakagadziridzwa uye yakagadziridzwa nekambani yedu ndeye 15-60μm; iyo yakajairwa particle size yecrystalline boron particles ndeye 1-10mm (yakakosha particle size inogona kugadzirwa zvinoenderana nezvinodiwa nevatengi). Kazhinji, yakakamurwa kuita zvirevo zvishanu maererano nekuchena: 2N, 3N, 4N, 5N, uye 6N.
