Gallium‘indium eutectic (often called EGaIn) is an alloy composed of gallium and indium in approximately a 75.5% to 24.5% ratio by weight. This low‘melting‘point metal has a melting temperature of around 15.7 °C, meaning it remains liquid at room temperature. Known for its excellent electrical and thermal conductivity, flowability, and compliance, gallium‘indium eutectic is frequently … Read more

Promethium is one of the rarest elements on Earth and belongs to the group of lanthanides, also known as rare earth elements. With the atomic number 61, it occupies a unique position on the periodic table as the only lanthanide that is radioactive but has no stable isotopes. Because it is both rare and unstable, … Read more

In chemistry, salts are more than just substances that flavor food. They are ionic compounds formed through the neutralization reaction between acids and bases. Among them, two important categories are hydrated salts and anhydrous salts. These terms refer to the presence or absence of water molecules within the crystal structure of a salt. Understanding the … Read more

Polonium is a fascinating and highly radioactive element that plays a significant role in the world of nuclear science and chemistry. First discovered by Marie and Pierre Curie in 1898, this element carries the symbol Po and holds atomic number 84. What makes polonium particularly intriguing is not only its scarcity and radioactivity, but also … Read more

Anhydrous copper sulphate is a significant chemical compound used in various industrial, agricultural, and laboratory applications.
