Metal oxide varistor is the core of the arrester, which main component is zinc oxide and with a small quantity of bismuth oxide, fluoride oxide, manganous carbonate, antimony oxide and other gleam of additive and made with high temperature.
Compared with traditional carborundun, mov(metal oxide varistor)has greatly mended voltage current characteristic and improved through-current capability, thereby to line up protection.
Natural Red Iron Oxide is the most widely occurring Minerals in Earth. It is widely used in many applications due as it is economical as compared to Synthetic Oxides.
Applications :
Red Oxide is anti-corrosive and has inertness to alkali and chemicals which makes its very viable for making of paint, protective coating for steels, cement coloring, NPK Fertilizers, paving tiles.
The Incinerated scrap or E46, is the by-product derived from the reprocessing of incinerated domestic waste.
After the combustion process, the furnace output (IBA Incinerator bottom ash) is firstly washed, magnetically separated and screened to separate any no ferrous material.
At a visual inspection, the material is fragmentized, with iron and steel parts, resulting partly cut or in shredded form.
The stock appears heterogeneous and contains all kind of cut or dismantled steel parts such as sheets, bars, frames, wires, bolts and other iron/steel household residues.
The incinerated scrap is eventually oxidized, due to the thermal and cooling treatments, that the material has been submitted to. The burnt scrap also contains minor slag parts, ash and iron oxide, due to the recovery process.
Such components are inherent and adhere to the scrap surface. The total impurities, can be sorted, but not fully removed.
The consignment does not contain any type of arms, ammunition, mines, shells, cartridges, radioactive contaminated, or any other explosive material in any form either used or otherwise.
The collected stock, is stored in open air, on cemented flooring. It can be loaded loose in 20â?? heavy duty container.

Iron oxide refers to a group of chemical compounds consisting of iron and oxygen atoms, and it comes in various colors, including red, yellow, and black. These compounds are commonly used as pigments in a wide range of applications, from coloring paints, ceramics, and plastics to tinting cosmetics and food products. Red iron oxide (Fe2O3) is often used for its rich, rust-red hue, while yellow iron oxide (Fe2O3�·H2O) provides a vibrant yellow color. Black iron oxide (Fe3O4) is employed as a dark pigment in inks and coatings. Beyond their coloring properties, iron oxides are also used in magnetic materials, catalysts, and as a source of iron in nutritional supplements. The versatility of iron oxide pigments and their ability to add color and functionality to various products make them essential compounds in many industries.
