What are the properties of quartz?
A natural material. Exceptional performance.
Used in electronics, technical glassware, and optics alike, quartz is a material with unique properties.
This silicon dioxide (SiO₂) glass, naturally present in the Earth’s crust, offers unmatched performance in many industrial and scientific fields.
But what exactly are its technical properties? Why is this material so highly sought after in extreme environments?
Here is an overview of its key advantages.
5 reasons to choose technical quartz for your critical industrial applications
In high-tech sectors, material selection leaves no room for chance. Faced with thermal, chemical, and optical constraints, fused quartz stands out as an essential solution. Here is why.
1. Exceptional material purity
Fused quartz is distinguished by an extreme purity level, reaching 99.99% silicon dioxide (SiO₂). This fundamental characteristic guarantees near-zero chemical reactivity and optimal resistance to contamination. At HTM Quartz, we process transparent and opaque quartz grades, ensuring rigorous traceability and strict raw material control to meet your highest requirements.
2. Outstanding thermal resistance
Capable of continuously withstanding extreme temperatures up to 1200°C, with possible peaks at 1300°C, quartz has a particularly low thermal expansion coefficient. It thus absorbs thermal shocks with a reliability far superior to that of standard glass or borosilicate. It is precisely this robustness that allows us to design cutting-edge equipment, such as our recent opaque quartz bell jars, specifically developed to guarantee perfect thermal homogeneity in ultra-high-temperature processing environments.
3. Formidable chemical inertness
Totally inert to the vast majority of chemicals and acids (with the exception of hydrofluoric acid and phosphoric acid H₃PO₄), this material is the ideal partner for highly corrosive environments. It integrates perfectly into the design of production chemical reactors, analysis vessels, or specialized equipment for research laboratories.
4. Remarkable optical transmission
From translucent to perfectly transparent depending on its finish, quartz offers excellent light transmission over a very broad spectrum, ranging from deep ultraviolet (160 nm) to infrared (5 µm). It is therefore highly prized for ultra-precision applications involving optical sight glasses and windows, spectroscopic cells, as well as laser systems and photonic components.
5. High dimensional stability
Thanks to its vitreous structure and very low expansion, quartz offers lasting dimensional precision, even when exposed to high temperatures. This non-deformability property is absolutely essential in the fields of microfabrication, optics, or electronics, where the slightest millimetric variation is unacceptable.
