Trivanadium sulfide

Trivanadium sulfide is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Trivanadium sulfide rather than just read about it. In short: Trivanadium sulfide is a metal rich sulfide of vanadium with chemical formula V3S. It is metallic in appearance and conductivity.

Key takeaways

Trivanadium sulfide belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Trivanadium sulfide to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Trivanadium sulfide from memory before moving on to harder problems.

Reference excerpt

Trivanadium sulfide is a metal rich sulfide of vanadium with chemical formula V3S. It is metallic in appearance and conductivity.

Properties V3S melts around 1360°C. V3S forms a eutectic mixture with vanadium with a composition in atom %: V 82.2%, S 17.8% melting at 1312°C. Although metallic, V3S is not known to be a superconductor.

Structure V3S is dimorphous.

Alpha form The alpha form α-V3S is stable over 950°C but can be quenched to a metastable state at room temperature. The crystals form in the body-centred tetragonal system with space group I42m with the unit cell dimensions: a = 9.470 c = 5.589 Å and unit cell volume of 501.2 Å3 with eight formula units per cell. Its density is 5.895 tonnes/m3. α-V3S is the prototype for a crystal structure type that includes AuPb3, Zr3Ir, Mo3P, and Ta3P.

Beta form The beta form β-V3S is stable below 825°C. The crystals form in the tetragonal system with space group P42/nbc with the unit cell dimensions a = 9.381 c = 5.939 Å, also with eight formulae per unit cell. Density is 5.939 tonnes/m3. β-V3S is the prototype for a crystal structure type that includes Ta3P.

Worked examples

Example 1 — a first encounter with Trivanadium sulfide

Start with the simplest possible case. Write down what Trivanadium sulfide claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Trivanadium sulfide before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Trivanadium sulfide ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Trivanadium sulfide

In research: Trivanadium sulfide appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Trivanadium sulfide in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Trivanadium sulfide is common in secondary-school and first-year university syllabi. It links to neighbouring topics Sulfides, Vanadium compounds, so understanding it makes those chapters shorter.
In everyday life: Look for Trivanadium sulfide outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
