Strontium Nitrate
Lub zog ntawm cev nqaij daim tawv
Tsis muaj kob los sis cov hmoov dawb, txheeb ze ntom ntom ntom 2.986.Melting point 570. Yooj yim zom rau hauv dej, kua ammonia, dej me ntsis soluble hauv anhydrous cawv thiab acetone. Txheeb rau emit oxygen los ntawm cua kub, thiab ua strontium nitrite, tshaj tawm cov pa roj carbon monoxide thiab nitrogen dioxide los tsim strontium oxide los ntawm cua kub ntxiv. Raws li oxidant, nws yuav ua rau kev sib tsoo thiab tawg yog tias sib cuag, rubs, tsoo nrog cov organic teeb meem lossis ntsib hluav taws, thiab tawg rau hauv cov nplaim taws carmine. Pauj kev chim!

Cov Kev Siv thiab Kev Siv
Siv rau ua hluav taws liab liab; teeb liab lub teeb ntawm hiav txwv-txoj kev, kev tsheb nqaj hlau thiab aerodrome; lub teeb liab plhaub, nplaim hluav taws sib tw thiab lub raj nplaim taws hauv kev tiv thaiv kev lag luam hauv teb chaws. Kuj tseem siv los ua aluminiferous tus neeg sawv cev ntawm kev ua yeeb yaj kiab kinescope thiab tsom iav. Tseem siv hauv tshuaj thiab siv cov tshuaj fluoroph.
Ntim Cov Lus
Ntim rau 25 lossis 50kg rau ib lub hnab (txheej ob lub hnab yas sab hauv, lub hnab ntim khoom sab nraud) lossis raws li cov neeg yuav tsum tau ua.
