Osmium compounds
Titanium is a chemical element found in abundance in nature occurring primarily in igneous rocks and secondary alluvial sands. It is the ninth most abundant element in Earth’s crust accounting for an average of 0.6 per cent by weight. It is a transition metal of Group 4 in the modern periodic tab......
The role of various components in the gold plating bath
Gold Plating Baths
Gold plating baths are aqueous solutions with optimised concentrations of specified salts and promoters, each of which is designed for different metals and alloys, for precision electroplating. In this article, the various constituents of gold plating baths, their functions, and......

Nickel Ore
Nickel ore is an important ore resource in nature, and it has wide application in scientific research and daily life. It is mainly used for processing of nickel and its alloys, and can also be used for processing of other metals and rare earth elements, providing effective raw materi......
Preparation of rhenium compounds
Abstract
This article focuses on the synthesis of rhenium compounds by means of organometallic chemistry and their applications in various fields. The most common approaches to synthesizing rhenium compounds are the Grignard reaction, the organometallic exchange reaction, and the reduction of rhe......
Chromite Oxidation Roasting
Chromite ore pyrolysis is an increasingly important process for economically recovering chromium from chromite bearing ores. Chromite ore pyrolysis occurs in several stages, with the thermal decomposition of the ore at relatively low temperatures. The pyrolysis reaction is endothermic due to the e......
Chromium Plating Hydrogen Embrittlement
Chromium is a chemical element with symbol Cr and atomic number 24. It is the first element in group 6. It is a steely-gray, lustrous, hard and brittle transition metal. Chromium is the main additive in stainless steel, to which it adds anti-corrosive properties.
Chromium is found naturally in th......
