CAS 7440-70-2
:Cálcio
Descrição:
Cálcio, com o símbolo químico Ca e o número CAS 7440-70-2, é um metal alcalino-terroso que é essencial para vários processos biológicos e industriais. É um metal macio, branco-prateado, que é relativamente reativo, particularmente com água e ácidos, formando hidróxido de Cálcio e gás hidrogênio. Em sua forma elementar, Cálcio é tipicamente encontrado na natureza como parte de compostos, como o carbonato de Cálcio em calcário e o sulfato de Cálcio em gesso. Tem um ponto de fusão de cerca de 842 graus Fahrenheit (450 graus Celsius) e um ponto de ebulição de aproximadamente 1.470 graus Fahrenheit (800 graus Celsius). Cálcio desempenha um papel crucial nos sistemas biológicos, particularmente na formação de ossos e dentes, bem como na contração muscular e na função nervosa. Em aplicações industriais, é usado em metalurgia, como agente redutor na extração de outros metais, e na produção de cimento e cal. Devido à sua reatividade, Cálcio deve ser armazenado sob óleo ou em uma atmosfera inerte para evitar oxidação.

CAS:Produto Controlado<p>Calcium is a chemical element with the symbol Ca and atomic number 20. It has an atomic weight of 40.078, which means that it is 40.078 times heavier than hydrogen. Calcium is an alkaline earth metal, as are magnesium and barium. Calcium is classified as a hard metal because it has a high melting point and its oxide layer resists corrosion by water and air. The ionized form of calcium (Ca2+) may be found in the cytosol, or in transport vesicles in muscle cells or other types of cells such as those of the intestine or bone cells. The main biological role of calcium ions is to maintain the potential difference across excitable cell membranes, enabling normal nerve transmission and muscle contraction, including the contraction of heart muscles. The concentration of calcium ions in extracellular fluid is tightly regulated by the kidneys under instruction from parathyroid hormone (PTH) and calcitonin hormones to keep blood calcium levels within a narrow range</p>Fórmula:CaPureza:Min. 95%Cor e Forma:Metal Or Metallic SolidPeso molecular:40.08 g/molCalcium granules (99.5%)
