In the iron industry, ferrous carbonate (FeCO3) is a valuable raw material because it can be reduced to elemental iron by hydrogen reduction. However, current industrial processes produce mixtures of FeCO3 and hematite (Fe2 O3) that are expensive, non-stoichiometric and sensitive to oxidation. This paper describes a new process for direct reduction of mineral iron …
Hafnium carbide, also known as HfC (hafnium-carbonide), is a chemical mixture of hafnium & carbon. This binary compound is among the least refractory. It has a melting point around 3900°C. The compound is resistant to oxidation, but it can be oxidized at temperatures as low and as high as 430°C. It may also be used …
Is it what you mean? Aluminum Boride ? Aluminum Boride can also be described as a binary mixture of Boron, Aluminum, and Boron. AlB2 is aluminum boride’s chemical formula. AlB2 is the chemical formula. At all temperatures and pressures, the material has a brownish-brown color. The material loses its surface shine when heated. Although it …
copper silicon is an important element for a number of applications in the electronic, aerospace, medical, marine, petrochemical and automotive industries. Known for its low electrical resistance, Cu has also become the material of choice for high-speed 3-D chip interconnects used in microprocessors.Effects of Si on the Uptake, Distribution and Homeostasis of Cu in Plant …
Selenide properties Selenides contain compounds with selenium anions. Se2-, which is similar to the sulfides can only occur in strong alkaline solutions. While it forms in neutral solutions, it becomes HSee-. In acid solutions, it becomes H2Se. Some metal selenides can react quickly with oxygen in the atmosphere, making them easier to breakdown than sulfides. …
The water-reducing agent should be used with concrete admixture, which will reflect the water-reducing effect. Cement quality is therefore a direct factor of the water reducing agent. When dealing with different types of “problem” cements, different strategies are required. High alkali cement High-alkali is a cement type with a large amount of alkali. Alkali in …

Active matter content (%): 82-82, and 98 About FMEE Fatty Metal Ester Ethoxylates : There are two types: P816 and 24-09. There are 2 types of P816 …
The Incas had lengthy included bismuth to an unique sort of bronze alloy reducing device, but also for long time bismuth was just slightly comprehended as well as was commonly puzzled with silver, lead and also tin. Bismuth'' s Latin name originates from the German word for white substance, however the metal bismuth is not …
Lithium stearate is a crystalline form of lithium. Lithium stearate has the chemical formula LiSt. It is a white powder that is solid at room temperatures. It is highly lubophilic and forms high light transmission at low concentrations. This compound is easily soluble in acetone and ethanol at room temperatures, but only slightly in water. …
calcium hypophosphite is a compound of calcium and phosphorus. It is used for various industrial purposes including electroplating, coating and chemical operations. Due to its explosive nature, calcium hypophosphite cannot be mixed with oxidants like nitrate or chlorate and should not be ground with quartz. It can also be used as a substitute for sulfuric …
