Superior corrosion resistance, no corrosion in acids 、 alkali and aqua regia. 具有优异的耐蚀性,各种酸、碱甚至王水(AR)都很难侵蚀它。
It is lead gray powder with good chemical stability, which is soluble in aqua regia, hot nitric acid and dense nitric acid and insoluble in dilute sulfuric acid and organic solvents. 高纯二硫化钼为铅灰色粉末,溶于王水(AR)、热硝酸及浓硝酸,不溶于水、稀硫酸及有机溶剂,化学稳定性好。
Being dissolved by aqua regia, concentrated by active carbon, and re-dissolved after incinerating to remove carbon, the amounts of palladium and gold in the samples can be directly analyzed by aas. 样品经过王水(AR)溶解、活性炭吸附富集、灰化除炭、再溶解等过程,利用原子吸收法,直接测定钯和金的含量。
In the chemical, the famous strong corrosive " aqua regia " can swallow silver, gold, as well as the known as the " stainless " in stainless steel erosion, becoming mottled rust beyond recognition. 在化学上,大名鼎鼎的强腐蚀剂“王水(AR)”能够吞噬白银、黄金,以至把号称“不锈”的不锈钢侵蚀,变得锈迹斑驳,面目全非。
The metal osmium is very stable in the air, the melting point is2700 degrees Celsius, it does not dissolve in the ordinary acid, will not be corroded in the aqua regia. 金属锇在空气中十分稳定,熔点是2700摄氏度,它不溶于普通的酸,甚至在王水(AR)里也不会被腐蚀。
