Nipa Boron Carbide Powder
Boron carbide lulú jẹ lile, dudu, bakanna bi didan. Lile rẹ kere ju ruby ​​ile-iṣẹ ṣugbọn o tobi ju carbide silikoni lọ. Boron carbide jẹ kere breakable ju awọn opolopo ninu apadì o. O ni gbigba neutroni igbona nla ti abala agbelebu, ati resistance kemikali to lagbara. Ko ṣe koko-ọrọ si ikọlu nipasẹ hydrogen fluoride gbona ati paapaa nitric acid. O ti wa ni tiotuka ni didà alkali ati ki o tun insoluble ninu omi ati ki o tun acid. Awọn iwuwo ojulumo (D204) jẹ 2.508 si 2.512. Idiwọn yo jẹ 2350 ℃. Ojutu farabale jẹ 3500 ℃.

Awọn ohun-ini Ẹmi-ara ti Boron Carbide Powder
Boron carbide ko ni fesi pẹlu acid ati ki o tun alkali ojutu ati ki o ni ga kemikali seese. O ni awọn ohun-ini ti gbigba neutroni, resistance-resistance, ati tun adaṣe semikondokito. O wa laarin awọn ohun elo ti o duro julọ si awọn acids bi o ṣe jẹ iduroṣinṣin ni gbogbo idojukọ tabi dilute acid tabi awọn ojutu omi ipilẹ. Boron carbide jẹ pataki ni aabo labẹ 800 ℃ agbegbe afẹfẹ.
Nigbati diẹ ninu awọn irin yipada ati awọn carbide wọn wa papọ, wọn ni iduroṣinṣin pataki. Awọn irin iyipada,, ati ninu tabili awọn eroja dahun ni agbara pẹlu boron carbide lulú lati ṣe awọn borides irin ni 1000 ~ 1100 ℃. Ni awọn ipele iwọn otutu ti o tobi ju, o ti royin pe boron carbide nigbagbogbo ma duro nitride tabi fesi pẹlu awọn irin oxides iyipada lati ṣẹda boron nitride ti o baamu ati paapaa borides, eyiti o jẹ aye ti ko wọpọ ati awọn hexaborides irin ipilẹ alkaline.
O ni lile Mohs ti o to 9.5 bi daradara bi ohun elo 3rd ti o nira julọ loye lẹhin ruby ​​ati tun cubic boron nitride, eyiti o nira diẹ sii ju silikoni carbide.
Nitori ilana iṣẹ igbaradi, boron carbide jẹ rọrun lati dagba awọn abawọn erogba, ti o mu abajade nla ti boron si awọn atunṣe ipin erogba lai ni ipa lori ilana gara, eyiti nigbagbogbo n mu iparun ti awọn ile ti ara ati ti kemikali tun wa. Iru awọn iṣoro bẹ nira lati yanju nipasẹ itusilẹ lulú bi daradara bi igbagbogbo nilo titration kemikali bakanna bi ipadanu pipadanu agbara.
