kvartsikruiskussa

Kvartsikruiskussa, a Finnish term, translates to "quartz crucible" in English. It refers to a laboratory or industrial vessel made from quartz, a crystalline form of silicon dioxide. Quartz crucibles are highly valued for their exceptional thermal stability and chemical inertness, making them suitable for high-temperature applications where other materials would degrade or react.

These crucibles are typically manufactured by melting high-purity quartz sand or by fusing quartz glass. The resulting material possesses a very low coefficient of thermal expansion, which allows it to withstand rapid temperature changes without fracturing. This property is crucial in processes involving extreme heat cycles, such as crystal growth or metallurgical refining.

The chemical resistance of quartz crucibles is another key advantage. They are resistant to most acids, bases, and solvents, even at elevated temperatures. This makes them ideal for melting, synthesizing, or analyzing materials that would corrode or contaminate vessels made from less resistant substances.

Common uses for quartz crucibles include semiconductor manufacturing, where they are used in crystal pulling processes for silicon and other semiconductor materials. They are also employed in the production of optical fibers, specialty glasses, and in various analytical chemistry procedures requiring inert and high-temperature containment. The purity of the quartz used directly impacts the purity of the materials processed within the crucible.
