CAS 7440-42-8

Boro

Descrição:

Boro, com o número CAS 7440-42-8, é um elemento metaloide que exibe características únicas. É tipicamente encontrado na natureza na forma de boratos e é conhecido por seu alto ponto de fusão e dureza. Boro tem uma densidade relativamente baixa e é um mau condutor de eletricidade à temperatura ambiente, mas pode exibir propriedades semicondutoras sob certas condições. Existe em vários alótropos, sendo as formas amorfas e cristalinas as mais comuns. Quimicamente, Boro é trivalente, o que significa que normalmente forma três ligações com outros elementos, e reage prontamente com oxigênio, nitrogênio e outros não-metais. Compostos de Boro, como ácido bórico e carbeto de Boro, são amplamente utilizados em várias aplicações, incluindo fabricação de vidro, cerâmica e como semicondutor em eletrônicos. Além disso, Boro desempenha um papel crucial em sistemas biológicos, particularmente no crescimento de plantas, embora sua função biológica exata ainda esteja sendo estudada. No geral, as propriedades únicas de Boro fazem dele um elemento importante tanto em contextos industriais quanto científicos.

Produto Controlado

CAS: 7440-42-8

Boron is a chemical element that has the symbol B and atomic number 5. Boron is a metalloid, which means that it has properties of both metals and nonmetals. It is not very reactive, so it does not combine with other elements to form compounds. Boron occurs in some plants, such as roses or wheat; in the soil; and in seawater. Boron can also be found in many foods, including raisins, almonds, and walnuts. Boron has been used as a nutrient solution for plants to increase their growth rate and improve the quality of their yield. The coordination geometry of boron varies depending on its environment. In biological samples boron can be detected using polymerase chain reaction (PCR) with magnesium salt as a stabilizer. Plasma mass spectrometry can also be used to detect boron. Active antiretroviral therapy has been shown to decrease levels of boron in plasma by 30%. Struct
