  • 毒性 :Occupational exposures may occur in its mining, smelting, and refining. The general population ingests nickel in food. Skin sensitization and dermatitis leading to chronic eczema, called “nickel itch,” frequently occurs, especially in wearers of pierced earrings. Nickel can also irritate the conjunctiva and respiratory tract mucous membranes. Absorption from the digestive tract is poor, so systemic poisoning is rare, but since it is an irritant it acts as an emetic. Systemic effects include hyperglycemia, capillary damage, CNS depression, myocardial weakness, and kidney damage. Nickel and its compounds are carcinogenic following inhalation, but not following ingestion or skin contact. Cancer of the lung and nasal passages results, with a latent period of about 25 years; smokers are at greater risk. In addition to irritation and carcinogenesis, nickel carbonyl (nickel tetracarbonyl, Ni(CO)4) exerts relatively mild, tran_x0002_sientinitial symptoms including headache, giddiness, nausea, and shortness of breath. These symptoms are followed by very serious symptoms hours to days later, consisting of tightness in the chest, shortness of breath, rapid respiration, pulmonary edema, cyanosis, and extreme weakness; this can be fatal. Heat decomposition of nickel carbonyl yields carbon monoxide. Chelating agents can be used to remove nickel from the body.

镍块性质、用途与生产工艺

  • 基本性质

    镍块是金属镍的一种形态,通常具有以下基本性质:
    镍块.jpg

    1. 密度高:镍块的密度约为8.9克/立方厘米,比铁、铜等许多金属都要重。

    2. 耐腐蚀性好:由于镍块具有优异的抗腐蚀性能,因此通常用于生产不锈钢、耐蚀合金等。

    3. 导电性能好:镍是一种优良的导电金属,因此镍块也具有优良的导电性。

    4. 熔点高:镍的熔点约为1455℃,因此具有较高的熔点,能够耐受高温环境。

  • 制备方法

    镍块的生产过程通常包括以下步骤:

    1. 镍的提纯:从镍矿中提取纯净的金属镍。

    2. 铸造成块状物:将纯净的金属镍熔融后,倒入模具中进行铸造,形成块状物。

    3. 熔炼和轧制:将铸造出的块状物放入炼钢炉中熔炼,然后进行轧制、拉伸等加工,最终形成各种规格的镍块。

  • 应用

    镍块被广泛应用于工业生产中,常见的应用包括:

    1. 生产锂离子电池:锂离子电池中使用的钴酸锂、三元材料等均需要使用镍块。

    2. 生产不锈钢:不锈钢通常含有大量铬、镍等元素,因此需要使用镍块作为原材料。

    3. 生产其他合金:镍块也可以用于生产其他金属合金,如耐腐蚀合金、高温合金等。
