FePO4 is widely recognized as iron phosphate. It has a great similarity to quartz that has trigonal lattice structure‚ space group P3121 (group no. 152). When the condition is under 980K‚ FePO4 becomes α-FePO4 that has trigonal lattice structure too and space group P3121 (group no. 152). In this form‚ phosphate‚ iron‚ and oxygen take up Wyckoff position 3a‚ 3b‚ and 6c correspondingly. Every phosphate or iron atom is united to four oxygen atoms‚ composing corner-connected FePO4 and PO4 tetrahedral

Rust is the name given to the common compound (Fe2O3) when iron combines with oxygen to form iron oxide. Rusting is known as corrosion of iron and its alloys such as steel or cast irons. Rust can be found on cars‚ metal pipes‚ aircrafts and anywhere with iron‚ copper and aluminium. Corrosion can be concentrated locally to form a split or crack‚ or it can extend across a wide area which causes corroding on surfaces. Because corrosion is a diffusion-controlled process‚ it occurs mainly on exposed surfaces

anode. My experiment is aimed at testing the corrosion of 2 different types of nails in a certain molar solution of salt water in anticipation of determining which of the two would be more suitable for beachside residencies. I hypothesized that the iron nails would almost double in content of rust as the molarity of the solution they’re soaked in increases. The galvanized nails hopefully will end up with limited amounts of rust in all solutions. The activity series plays a major role in corrosion

Ukraine is rich in natural resources: coal‚ iron ore‚ manganese‚ nickel and uranium‚ and others. The reserves of sulfur are the largest in the world‚ the reserves of mercury ore are the second largest. Also more than 5% of world reserves of iron ore are concentrated in Ukraine. There are oil and gas deposits but their reserves are not significant (the reserves of these fossil fuels were partly depleted during the Soviet period). Coal is the main fossil fuel of Ukraine. It is mined in the Donetsk
