Màndarga ak jëfandikoo Hydroxyde de Magnesium

Hydroxyde de magnésium (Mg(OH)2) poudre amorphe bu weex la wala kristal hexagonal. Dafay dëgër ci wàllu chimik, te amna màndarga physique ak chimique yu baax, loolu dafay wane njariñu jëfandikoo gi ci wàll yu bari.

Ci wàllu physique, hydroxide magnesium dafa am densité bu néew (ci diggante 2.36 g/cm3), point de fusion bu kawe (decomposition ci 350 degre), ak ay isolation yu baax. Jariñu kristal bi dafa am ay diisaay, am lëkkaloo hydrogen ci digganté diisaay yi, loolu tax mu mëna wéy di dëgër doonte tàngoor wi yéeg na lool. Rax ci dolli, hydroxyde magnesium amna surface bu yaatu, te loolu mën na indi jafe-jafe ci adsorption bi ak ci reaction bi.

Ci wàllu chimie, hydroxyde de magnésium base bu néew doole la, te daa néew lumuy seey (ci diggante 0.0002 mol/L ci 25 degre). Kon dafay wane alkalinité bu woyof ci biir ndox, moo tax mu baax ci environmaa yi soxla corrosivité bu néew. Doonte du seey ci ndox, mingi seey ci asid ngir sos xorom magnesium ak ndox. Màndarga boobu moo waral ñu koy jëfandikoo bu baax ci wàllu aar environmaa bi, muy luy dindi gaz asid yu baaxul yi ak ndox mu baaxul mi. Rax ci dolli, hydroxyde magnesium amna tàngoor wu metti ngir seey (dafay tàmbali ci 340 degre ngir seey nekk oxide magnesium ak ndox), te seey gi dafay endothermic, muy tere lakk bi. Moo tax ñu koy faral di jëfandikoo ngir tere xal yi tàkk.

Li hydroxide magnesium amul toxisite bu bari te baaxna ci environmaa bi moo tax ñu koy wut bu baax ci defarkati garab yi, lekk yi ak plastik yi. Ci misaal, ci wàllu farmasi, mën nañu ko jëfandikoo muy antacide ak laxatif; ci plastik ak kawsu, mën nañu ko jëfandikoo muy filler retardant flame ngir gëna baaxal macceer yiy xeex lakk te du yàq seen doole mekanik.

Ci gàttal, hydroxide magnesium, ak stabilite thermique bu rëy, toxisite bu néew, ak inert chimik bu baax, amna njariñ yu am solo ci wàllu retardansi xal, aar environmaa bi, medsin, ak science matériel. Ak jëm kanam gi ci xarala yi, dina ñu gëna jàngat njariñ li ci nekk.
