Let’s begin with a question that might come in both prelims and mains: Why does India give so much importance to Thorium, even though Uranium is used as nuclear fuel today? The answer lies in a combination of resource availability, reactor design, and strategic foresight—as we shall now explore. What is Thorium? Thorium is a…
Uranium is a silvery-grey metallic radioactive element, found naturally in the Earth’s crust. It is one of the most crucial atomic minerals due to its role in nuclear energy production and defence technology. But what makes uranium so important? Uranium Isotopes and Fissility Uranium exists in nature in the form of two main isotopes: Here…
Let’s begin with a simple idea. See, just like iron is a metallic mineral and limestone is a non-metallic mineral, atomic minerals form a third category. These are minerals that contain radioactive elements like uranium, thorium, radium, and some rare earth elements (REEs). The term atomic is used because these minerals are the source of…
Gypsum is a hydrated calcium sulphate mineral with the chemical formula CaSO4·2H2O. There are different varieties of gypsum based on texture and appearance, including: Unique Physical Property Gypsum’s industrial importance comes from its ability to lose about 75% of its combined water of crystallisation when heated moderately to around 130°C. This process is called calcination….
Sillimanite is a naturally occurring alumino-silicate mineral, with the chemical formula Al₂SiO₅. ➡️ It is one of three polymorphs of aluminium silicate — the other two being Kyanite and Andalusite.Polymorphs = same chemical composition but different crystalline structures, formed under different pressure-temperature conditions. Geological Formation of Sillimanite Where does it come from? Industrial Applications of…
Kyanite is a blue to greenish-blue mineral, typically found in metamorphic rocks that are rich in aluminium. ➡️ Geological Nature: Key Physical and Industrial Properties Property Details High Refractoriness Can withstand extremely high temperatures without deforming or breaking. Aluminium Content The higher the aluminium, the better the quality of kyanite — making it valuable for…
Asbestos refers to a group of six naturally occurring fibrous silicate minerals, known for their extreme durability and resistance. These minerals are not one single mineral, but a category defined by their fibrous crystal structure. Key Physical Properties: Property Importance Fibrous texture Can be woven into cloth or rope. Flexibility & Tensile Strength Strong yet…
Let’s start with a fundamental definition. Mica is a naturally occurring, non-metallic phyllosilicate mineral — that is, a silicate mineral which forms in layers (phyllo = leaf in Greek). ✅ It is one of 34 phyllosilicate minerals, but only a few — like Muscovite and Phlogopite — are economically significant. Now, what makes mica special?…
After discussing dolomite, which contains both calcium and magnesium, we now turn to a mineral that is almost purely magnesium carbonate — Magnesite. What is Magnesite? Let’s begin with the textbook definition: Magnesite is a magnesium carbonate mineral with the chemical formula: MgCO₃ It usually forms in magnesium-rich rocks and comes in three common forms:…
In the last section, we’ve talked about limestone. Now, imagine a close cousin of limestone — similar in structure, but with a subtle chemical twist. That’s Dolomite. What is Dolomite? Let’s begin with the technical identity: Dolomite is a mineral compound made up of calcium magnesium carbonate with the formula:CaMg(CO₃)₂ If limestone is primarily calcium…
