High purity quartz sand content required for quartz crucible

date icon

Quartz crucible is a heat-resistant container commonly used in laboratories. Its main component is silica (SiO2). Quartz crucible has high temperature resistance, corrosion resistance and chemical stability, and is widely used in experimental operations such as high-temperature smelting, ash content determination, rock analysis, and metal substance ablation.

Quartz crucible requires high purity quartz sand
Since quartz crucibles need to withstand high temperatures and corrosive environments during use, the purity of the material is very high. Ordinary quartz sand may contain impurities, such as iron oxide, aluminum oxide, etc. These impurities may affect the experimental results and cause cracks and damage on the surface of the quartz crucible.
Therefore, a quartz crucible requires a quartz sand content of at least 99.9%. Such high-purity quartz sand can ensure the quality and performance of quartz crucibles and improve the accuracy and reliability of experiments.

Quartz crucible care and maintenance
In order to ensure the service life and quality of the quartz crucible, some maintenance issues need to be paid attention to. First of all, check whether the quartz crucible is damaged or cracked before use to avoid failure of the experiment due to bursting at high temperatures. Secondly, it needs to be cleaned promptly after use to remove residues and contaminants to avoid affecting the next experiment.
