Fa'amatalaga Puupuu

Boron carbide (fuafuaga fa'a-kemikolo e tusa ma le B4C) o se mea e sili ona malosi ma faigata na fa'aaogaina e le tagata e fa'aaogaina e pei o se mea fa'afefete ma fa'amalosi ma i totonu o la'au fa'atosina i masini faaniukilia, vili ultrasonic, u'amea ma le tele o talosaga tau alamanuia. Faatasi ai ma le maaa Mohs e tusa ma le 9.497, e o se tasi o mea sili ona faigata ua iloa, i tua atu o le boron nitride kupita ma taimane.O lona tulaga tulaga ese e matua faigata. corrosion teteʻe i le tele o vailaʻau faʻafefe, malosi vevela sili, kalave patino maualalo ma maualuga modulus elastic.

Talosaga

Boron Carbide e fetaui lelei i le tele o mea tau pisinisi e aofia ai:

Abrasive mo le lapping ma ultrasonic tipi, Anti-oxidant i carbon-bonded refractory mixes, Armor Nuclear talosaga e pei o reactor pulea rods ma neutron mitiia talipupuni.

La'ei vaega e pei o fa'asu'u fe'ai, pa'u e tusi uaea, u'amea fa'a pauta ma mea fau sima, ta'iala filo.

E faʻaaogaina e avea o se faʻaopoopoga i le faʻaauau pea o le lafo o refractory ona o lona maualuga maualuga ma le mautu vevela.

Fa'agasologa o Gaosiga

Boron Carbide o loʻo faʻafefeteina mai le boric acid ma le kaponi pauta i totonu o le ogaumu eletise i lalo ole vevela maualuga.O se tasi o mea e sili ona faigata e fai e tagata o lo'o maua i fa'atauga fa'atau e iai lona tau liusuavai e maualalo e fa'ataga ai lona fa'afaigofie ona fa'apena i foliga.O nisi o mea fa'apitoa a Boron Carbide e aofia ai: maualuga le ma'a'a, fa'ama'i fa'ama'i, ma le maualuga o le neutron e mitiia, vaega fa'asaga.
