In today’s rapidly evolving technological landscape, industries are constantly seeking materials that can withstand the harshest conditions. Whether it’s in aerospace, automotive, energy, or defense sectors, the demand for high-performance materials is ever-increasing. One such material that has gained significant attention is silicon carbide (SiC). Silicon carbide products have emerged as a game-changer, offering exceptional properties that enhance performance in extreme environments.

Early lithium batteries used metallic potassium as the negative electrode. Since potassium is an alkali metal and has low density, it has a high electrochemical equivalent (3860mA·h/g) and the most negative electrode potential (-3.045V).

Cemented carbide: Cemented carbide is a material made by powder metallurgy with the powder of one or several refractory carbides as the main component, adding cobalt powder for bonding. Commonly used cemented carbides are divided into tungsten-cobalt, tungsten-cobalt-titanium, and tungsten-titanium-tantalum (niobium) based on their composition and performance characteristics. Carbide has high hardness, high thermal hardness, good wear resistance and high compressive strength, but low bending strength and poor toughness. Good corrosion resistance and oxidation resistance. The linear expansion coefficient is small, but the thermal conductivity is poor.

Platinum crucible Platinum is often used because of its many excellent properties. The melting point of platinum is as high as 1774°C and its chemical properties are stable. It does not undergo chemical changes after burning in the air and does not absorb moisture. Most chemical reagents are resistant to it. No corrosive effect.

Alumina ceramics are ceramic-like materials composed of AI203 as the main raw material and corundum (a-AI203) as the main mineral. The AI203 content is generally 75.0% ~ 99.9%. High-purity alumina ceramics (AI203 content is higher than 99%)

Features of alumina ceramic crucible: It can withstand heat up to about 1200 degrees and is suitable for melting samples of acidic substances such as K2S207. Generally, it cannot be used for melting with Na0H, Na202, Na2CO3 and other alkaline substances as flux to avoid corrosion of the porcelain crucible. Porcelain crucibles cannot come into contact with hydrofluoric acid.

Silicon carbide crucible is a type of crucible. It is a relatively deep bowl-shaped container with a ceramic texture. Why use a crucible? Because glassware cannot withstand the high temperatures when heating solids,

The principle of heat recovery and utilization in high-temperature kilns is to use a heat exchanger to extract heat energy from the exhaust gas to generate hot air, hot water or steam, thereby achieving energy saving.
