Surfactants are a class of compounds that reduce the surface tension of a liquid. They can be adsorbed on gas-liquid or liquid-liquid interfaces, thus changing the properties of the interface and affecting its stability, wettability, viscosity, surfa...…
What is Manganese oxide?Manganese oxide minerals have been used for thousands of years—by the ancients for pigments and to clarify glass, and today as ores of Mn metal, catalysts, and battery material. More than 30 Mn oxide minerals occur in various ...…
What is manganese dioxide?The type of manganese dioxide (MnO2) and its quantity used in dry cells are mainly responsible for cell capacity. Performance characteristics depend on individual crystal structure, varying degrees of hydration, and the acti...…
Since Pietzka and Schuster first synthesized Ti3AlC2 bulk materials by sintering cold-compacted powder mixtures of Ti, TiAl, Al4C3, and C at 1300 °C in pure hydrogen for 20 h [1], various methods have been attempted to synthesize Ti3AlC2 bulk materia...…
Many processes have been developed for manufacturing Si3N4 powder, including a direct nitration process of silicon powder, a silicon diimide process, a carbothermal reduction and nitration process using SiO2 powder, a gas phase reaction process, a pl...…
Calcium hexaboride (CaB6) is a divalent alkaline-earth cubic hexaboride characterized by low density (2.45 g/cm3 ), high melting point (2235°C), high hardness/Young’s modulus [27 GPa (Hv)/379 GPa], high electrical conductivity, as well as good chemic...…
Bismuth telluride is the dominant thermoelectric material for applications near room temperature due to its inherently low lattice thermal conductivity and high electronic weighted mobility. Its performance is ultimately limited by the harmful effect...…
The binary compound nitride is made up of nitrogen and an element which has a lower electronegativity. Nitrogen, which has a high electronegativity can form a number of nitrides when combined with other elements that have fewer electronegativity. Thi...…
Foaming the agent is a substance that can make its aqueous solution produce a large amount of foam under the condition of introducing air by mechanical force. This kind of substance is surfactant or surfactant. The essence of a foaming agent is its s...…
There are many substances that can produce foam, but not all substances can produce foam can be used as the cement foaming agent. The foaming agent shall have sufficient stability to ensure that the foam will not break during mixing with the mortar a...…
The water content of Opal is not fixed, generally about 3%-10%, but there are as high as 20%; Hardness is 5-5.5; Specific gravity is 1.9-2.5; Generally, egg white, if there are other atoms mixed, can form a variety of colours, such as iron, calcium, ...…
Titanium-aluminum carbide is a new type of layered ceramic material with unique properties, which has been widely concerned by material scientists and physicists. Titanium carbide aluminum (Ti3AlC2) belongs to the hexagonal crystal system and has the...…
Nano silver colloidal This is simply a metallic silver substance with a small particle size of around 1-100nm. Most nano-silver particles are around 20 nanometers in size, but a small number can go below 5 nanometers. Nano-silver has an effective br...…
Foam concrete wall casting methods can be divided into three types: removable formwork casting, formwork-free casting and sandwich wall casting. Among these three types of casting methods, the mold-free casting method is widely used.…
The coating material for the lithium battery's diaphragm is High purity micro alumina. It acts as an insulation and heat resistant coating. Additional ingredients for lithium battery cathode materials: Doped with lithium cobalt, lithium manganate,...…
