一般說明

碘是一种深灰色固体,会升华成紫色气体。对于固体,碘分子具有高蒸汽压(0.31 mmHg at 25 °C)化学上,碘是亲电的,可参与亲电取代反应,如碘化有机化合物。这种亲电行为是由于碘原子具有高电负性和较大的尺寸,这使得它成为相对弱的氧化剂。我们合成的高纯度碘含有少于100 ppm的痕量金属杂质。

應用

高纯度碘在制药、化学和电子工业领域有多种用途。在半导体和电子工业中,高纯度碘用于生产半导体,它作为掺杂剂制造p型半导体和LCD显示器。在生命科学行业,高纯度碘用于生产X-射线造影剂,它可增强医学成像时特定器官的可见度。碘还在各种医疗应用中被用作消毒剂、抗真菌剂和防腐剂。其独特的特性使其成为各种高科技应用中的重要元素,在这些应用中,其高纯度是必不可少的。

特點和優勢

我们99.99%纯度的碘适用于制药,化学和电子工业,这些纯度最重要的领域。
✔ 品质始终如一
✔ 高纯度
✔ 可用于放大实验:批量和中试生产
