Alumina vs Platinum CruciblesTemperature · Chemistry · Cost · Best useAluminaPlatinumA practical guide by Labmina · Updated 2026 Platinum is the gold standard for trace-level analytical work; alumina is the affordable, high-temperature ceramic for everything else. Platinum offers near-perfect inertness at a very high price; alumina delivers excellent performance for most lab work at a

Alumina vs Porcelain CruciblesTemperature · Chemistry · Cost · Best useAluminaPorcelainA practical guide by Labmina · Updated 2026 Porcelain crucibles are the cheap classroom standard; alumina is the higher-performance upgrade. Alumina handles far higher temperatures (~1600°C vs porcelain’s ~1200°C), resists thermal shock and contamination better, and lasts longer — at a modestly higher price. This

Alumina vs Graphite CruciblesTemperature · Chemistry · Cost · Best useAluminaGraphiteA practical guide by Labmina · Updated 2026 Alumina and graphite are both common crucibles for melting metal, but they win in opposite conditions. Alumina is the clean, oxidising-stable ceramic; graphite is the fast, conductive choice that only works under inert atmospheres. The deciding factors

Alumina vs Quartz Crucibles Temperature · Purity · Chemistry · Cost Alumina Quartz A practical guide by Labmina · Updated 2026 Alumina and quartz are two common crucible and labware materials, but they suit very different jobs. Alumina is the high-temperature ceramic (rated to ~1600°C); quartz (fused silica) is the transparent, ultra-pure option limited to

Clean & Care for Alumina Crucibles Condition · Clean · Extend lifespan A practical guide by Labmina · Updated 2026 An alumina crucible is a reusable tool, not a consumable to throw away after one run — treated well, a 99% high-purity alumina crucible lasts for many high-temperature cycles. The keys are conditioning it before

Alumina Crucibles for Melting Metal Gold · Silver · Copper · Aluminium & more A practical guide by Labmina · Updated 2026 Alumina crucibles are a popular, low-cost choice for melting metals in the lab and small foundry — but only for the right metals. Because 99% high-purity alumina is chemically inert with most molten

Crucible Material Selection Guide Alumina · Zirconia · Quartz · Graphite · Platinum AluminaZirconiaQuartzGraphitePlatinumA practical guide by Labmina · Updated 2026 There is no single “best” crucible material — only the best material for your specific job. The five you will meet most often in a laboratory are alumina, zirconia, quartz, graphite and platinum, and

Choosing a Crucible for TGA & Thermal Analysis Material · Volume · Instrument compatibility A practical guide by Labmina · Updated 2026 The crucible you run a TGA or DSC sample in is not a trivial choice. The wrong material can react with your sample and distort the mass-loss curve; the wrong volume wastes sample

Alumina or zirconia crucible? Compare maximum temperature, chemical resistance, thermal shock and cost — and see which material fits your application.
