Lanthanum carbonate

Lanthanum carbonate 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 Lanthanum carbonate rather than just read about it. In short: Lanthanum carbonate, La2(CO3)3, is the salt formed by lanthanum(III) cations and carbonate anions. Chemistry Lanthanum carbonate is used as a starting material in lanthanum chemistry, particularly in forming mixed oxides, for example for production of lanthanum strontium manganite, primarily for solid oxide fuel cell applications; for production of certain high-temperature superconductors, such as La2-xSrxCuO2.

Key takeaways

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

Reference excerpt

Lanthanum carbonate, La2(CO3)3, is the salt formed by lanthanum(III) cations and carbonate anions.

Chemistry Lanthanum carbonate is used as a starting material in lanthanum chemistry, particularly in forming mixed oxides, for example

for production of lanthanum strontium manganite, primarily for solid oxide fuel cell applications; for production of certain high-temperature superconductors, such as La2-xSrxCuO2.

Medical uses Lanthanum carbonate is used in medicine as a phosphate binder. As a medication it is sold under the trade name Fosrenol by the pharmaceutical company Shire Pharmaceuticals. Due to its large size (1000 mg tablet is 2.2 cm in diameter), it may be possible to choke on the tablet if it is not chewed. It is prescribed for the treatment of hyperphosphatemia, primarily in patients with chronic kidney disease. It is taken with meals and binds to dietary phosphate, preventing phosphate from being absorbed by the intestine. For cats with hyperphosphatemia it is available under the trade name Renalzin by Bayer Animal Health. However, when lanthanum carbonate is used for treating hyperphosphatemia, its side effects, namely myalgia, muscular cramping, and peripheral edema, should be clinically monitored.

Other applications Lanthanum carbonate is also used for the tinting of glass, for water treatment, and as a catalyst for hydrocarbon cracking.

Worked examples

Example 1 — a first encounter with Lanthanum carbonate

Start with the simplest possible case. Write down what Lanthanum carbonate 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 Lanthanum carbonate 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 Lanthanum carbonate 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 Lanthanum carbonate

In research: Lanthanum carbonate 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 Lanthanum carbonate 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: Lanthanum carbonate is common in secondary-school and first-year university syllabi. It links to neighbouring topics Carbonates, Drugs developed by Takeda Pharmaceutical Company, Lanthanum compounds, so understanding it makes those chapters shorter.
In everyday life: Look for Lanthanum carbonate 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.
