About: Massicot

An Entity of Type: mineral, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Massicot is lead (II) oxide mineral with an orthorhombic lattice structure.Lead(II) oxide (formula: PbO) can occur in one of two lattice formats, orthorhombic and tetragonal. The tetragonal form is called litharge. PbO can be changed from massicot to litharge (or vice versa) by controlled heating and cooling. At room temperature massicot forms soft (Mohs hardness of 2) yellow to reddish-yellow, earthy, scaley masses which are very dense, with a specific gravity of 9.64. Massicot can be found as a natural mineral, though it is only found in minor quantities. In bygone centuries it was mined. Nowadays massicot arises during industrial processing of lead and lead oxides, especially in the glass industry, which is the biggest user of PbO.

  • El massicot és un mineral de plom i oxigen, l'òxid de plom(II) de fórmula química PbO, de color groc sofre, duresa 2 i una densitat de 9,64 g/cm³, cristal·litza en el sistema ortoròmbic. El nom és francès i prové delcastellà mazacote, aquest de l'àrab masḥaqūniyā, i aquest del siríac mšaḥ qūnyā, literalment, "ungüent de sosa". Segons la classificació de Nickel-Strunz, el massicot pertany a "04.AB: Òxids amb proporció Metall:Oxigen = 2,1 i 1:1, amb M:O = 1:1 (i fins a 1:1,25); amb cations grans" juntament amb els següents minerals: swedenborgita, brownmil·lerita, srebrodolskita, montroydita, litargiri i romarchita. Existeix un altre mineral d'òxid de plom (II), anomenat litargiri, que es diferencia del massicot en l'estructura cristal·lina i en les propietats físiques. (ca)

Massicot can be found as a natural mineral, though it is only found in minor quantities. In bygone centuries it was mined. Nowadays massicot arises during industrial processing of lead and lead oxides, especially in the glass industry, which is the biggest user of PbO. The definition of massicot as orthorhombic PbO dates from the 1840s, but the substance massicot and the name massicot has been in use since the late medieval era. There is some evidence that the ancient Romans used the substance. It may occur as an oxidation product of other lead-bearing minerals such as galena, bournonite, boulangerite, either naturally or in industrial processing. When massicot is found in a natural environment, some other minerals that may be found with it may include cerussite, litharge, minium, wulfenite, valentinite and limonite. (en)

  • 黄丹(英語:Massicot)是具有正交晶系结构的含铅氧化物矿物。一氧化铅有两种不同的晶形。四方晶系的被称为密陀僧。通过控制加热和冷却,PbO可以从黄丹变为密陀僧,反之亦然。在室温下,黄丹形成柔软的(莫氏硬度为2)黄色至红黄色,土状或鳞片状的物质,比重为9.64。黄丹可以作为一种天然矿物被发现,尽管数量很少。 它可能作为其他含铅矿物的氧化产物,例如方铅矿、车轮矿、硫锑铅矿等。当在自然环境中发现黄丹时,可能一起发现的部分其他矿物如白铅矿、密陀僧、铅丹、、锑华和褐铁矿等。 (zh)
