Rust

Rust is an iron oxide, usually red oxide formed by the redox reaction of iron and oxygen in the presence of water or air moisture. Several forms of rust are distinguishable both visually and by spectroscopy, and form under different circumstances. Rust consists of hydrated iron(III) oxides Fe₂O₃·nH₂O and iron(III) oxide-hydroxide (FeO(OH), Fe(OH)₃).

Given sufficient time, oxygen, and water, any iron mass will eventually convert entirely to rust and disintegrate. Surface rust is flaky and friable, and it provides no protection to the underlying iron, unlike the formation of patina on copper surfaces. Rusting is the common term for corrosion of iron and its alloys, such as steel. Many other metals undergo equivalent corrosion, but the resulting oxides are not commonly called rust.

Other forms of rust exist, like the result of reactions between iron and chloride in an environment deprived of oxygen. Rebar used in underwater concrete pillars ,which generates green rust, is an example.

Chemical reactions

Iron oxide

Iron oxides are chemical compounds composed of iron and oxygen. All together, there are sixteen known iron oxides and oxyhydroxides.

Iron oxides and oxide-hydroxides are widespread in nature, play an important role in many geological and biological processes, and are widely used by humans, e.g., as iron ores, pigments, catalysts, in thermite (see the diagram) and hemoglobin. Common rust is a form of iron(III) oxide. Iron oxides are widely used as inexpensive, durable pigments in paints, coatings and colored concretes. Colors commonly available are in the "earthy" end of the yellow/orange/red/brown/black range. When used as a food coloring, it has E number E172.

Fobia

Fobia is a Mexican Rock en Español band from Mexico City. The current line-up includes vocalist Leonardo de Lozanne and guitarist and lead songwriter Francisco "Paco" Huidobro. The rhythm section is made up of ex La Ley drummer Mauricio Claveria, former Caifanes, Jaguares, and La Barranca bassist Federico Fong, and keyboardist Dario González Valderrama.

History

The band was formed in 1987 by Lozanne and Huidobro, brother of Micky Huidobro of Molotov. The original lineup consisted of Lozanne, Huidobro, bassist Javier Chá Ramirez, keyboardist Iñaki Vazquez, and Gabriel Kuri on drums. Kuri was later replaced by Jorge ‘la Chiquis’ Amaro who was followed by multi-instrumentalist Jay de la Cueva, (lead singer of the Mexican hair band Moderatto).

Fobia was one of the original Rock en Español bands to emerge from the Mexican Rock en Español / Rock en tu idioma (Rock in your language) boom of the late 1980s, alongside Caifanes, Maná, Neón, Maldita Vecindad y los Hijos del Quinto Patio and Los Amantes de Lola; all of which followed in the footsteps of Soda Stereo – who by the late 1980s had amassed a huge following in the Americas. In December 1987, RCA Ariola de México held a "Rock en tu idioma" battle of the bands contest in Mexico City. Fobia was eliminated early on and Los Amantes de Lola went on to win the contest. In spite of their early elimination, executives from Ariola decided to schedule an appointment with Fobia. According to legend, the band missed their meeting with Ariola because they weren't able to enter the building due to problems with security. Following the incident, the band's luck improved. Saúl Hernández of Caifanes produced their first demos and Ariola eventually signed them.

Fobia (album)

Fobia is an album released by Mexican rock band Fobia. Their self-titled debut album was released in 1990. The songs are primarily themed around common phobias and anxieties, filled with dark humor and melodic music inspired by British bands like The Cure. Songs like Los muñecos and Las moscas deal with the fear of dolls and flies respectively. Other songs like Dios bendiga a los gusanos and El crucifijo deal with the anxieties of love. El microbito delivers humor and a quick change of pace towards the album's finale. It is worth noting that the songs listed above are all hits.

The band received critical and commercial success, added to the fact that Rock en español was going through a revival at the time and new bands seemed to come out of the woodwork.

The original lineup was:
