Overview and properties of manganese silicide

How serious are fertility problems today? People don't want to give birth,can't afford it, and can't give birth that has become the "three mountains".
The problem of childbirth is related to the people's livelihood. Whether a country can prosper or not depends on the population. I saw a set of data a few days ago. The data shows that on January 1, 1990, 2,784 babies were born in Shanghai. Ten years later, on January 1, 2000, 1,148 babies were born in Shanghai. In 2010, the number became 380. , 2020 only 156 people, the decline in the birth rate is shocking. The three most critical reasons are: I don't want to give birth, I can't afford it, I can't give birth! The decline of the global population will bring a series of economic and social problems, among which the demand for manganese silicide, manganese silicide overview, manganese silicide application, manganese silicide suppliers, manganese silicide price will also be affected.

Manganese Silicide Overview

Manganese silicide, molecular formula: MnSi2, English name: manganese disilicide, inorganic compound, gray octahedral crystal, density: 5.24g/mL, soluble in hydrofluoric acid, alkali, insoluble in water, nitric acid, sulfuric acid.

Manganese silicide synthesis method

2 g (0.036 mol) manganese, 2 g (0.071 mol) silicon and 10 g (0.16 mol) copper are placed in small pieces in a 10 mL Al2O3 crucible and placed in a quartz ampoule with one end open. After evacuation and sealing, the ampoules are placed in a high-temperature furnace of carbon silicon rods. The temperature was raised to 1200°C within 12h, and then lowered to 500°C at a rate of 10°C/h. The ampoule is removed, cooled, and inserted into a thicker diameter rubber tube, breaking the ampoule so that the metal ingot can be safely removed. The copper-rich Cu—Mn—Si matrix was dissolved in 8 mol/L nitric acid, and the octahedral crystals remained. These crystals were washed with water and dried to obtain MnSi2 crystals with an edge length of 2 mm.

Manganese Silicide Properties and Stability

Soluble in hydrofluoric acid and alkali, insoluble in water, nitric acid and sulfuric acid.

Application of manganese silicide MnSi2 powder

Due to its unique physical and chemical properties, manganese disilicide (MnSi2) has been successfully used in materials and photovoltaic materials in the fields of complementary metal oxide semiconductor elements, thin film coatings, bulk structure elements, electric heating elements, thermoelectric elements, etc.

Using manganese silicate thermoelectric conversion material, the power factor of power generation capacity is 2.4mW/K2m, which is about twice the original power. Manganese disilicide (MnSi2) is also expected to convert waste heat at 300-700°C and other waste heat into electricity for use in engines and industrial furnaces and in the field of industrial furnaces for high-power thermoelectric power generation modules.
