About Silica Crucibles

A silica crucible is a heat-resistant container made primarily from high-purity silicon dioxide (SiO), commonly known as fused silica or quartz. It is used in laboratories and industrial processes for heating, melting, or chemically treating materials at high temperatures.

Exceptional Thermal Shock and Chemical Resistance

These silica crucibles boast excellent resistance to rapid temperature swings and most acids (excluding hydrofluoric acid), making them dependable for dramatic heating and cooling cycles. Their fused construction ensures minimal thermal stress, allowing repeated usage in challenging environments such as laboratories, industrial furnaces, and metal casting plants.

Crafted for Precision and Purity

Manufactured via fused, flame-fused, or slip-cast processes, each crucible exhibits a smooth, non-porous surface and a high purity level greater than 99.8%. This ensures minimal contamination for delicate samples and refined metal or glass production, meeting stringent analytical and industrial requirements.

Engineered for Consistent Electrical Insulation

With superior insulating properties even at elevated temperatures, these crucibles prevent electrical interference during sensitive measurements. Their neutral pH and translucent/white appearance support reliable and observable experimental setups across varied high-temperature applications.

FAQ's of Silica Crucibles:

Q: How do silica crucibles provide resistance to thermal shock and chemical corrosion?

A: Silica crucibles are engineered with excellent thermal shock resistance, enabling them to endure rapid temperature changes without cracking. Their high purity fused silica composition resists chemicals and acidic environments (except hydrofluoric acid), making them ideal for harsh laboratory and industrial conditions.

Q: What is the recommended process for cleaning and reusing these crucibles?

A: After use, allow the crucible to cool gradually before cleaning. Rinse with mild acid (avoid HF), then thoroughly wash with water and dry. Avoid thermal shock during cleaning, and only reuse if the crucible remains intact and uncontaminated.

Q: When should I choose a fused silica crucible over other materials?

A: Select a fused silica crucible when your application demands resistance to high temperatures up to 1700C, thermal shock, chemical corrosion, and superior electrical insulation - particularly for laboratory analysis, industrial furnaces, metal casting, or glass production.

Q: Where should these crucibles be stored for longevity and performance?

A: Store silica crucibles in a dry, cool place away from sources of moisture to maintain stability and prevent contamination. Proper storage extends their shelf life and preserves their high purity and non-porous characteristics.

Q: What are the benefits of the smooth, non-porous finish on these crucibles?

A: A smooth, non-porous surface minimizes sample contamination and chemical absorption, improving sample recovery and ensuring reliable, repeatable laboratory and industrial results.

Q: How can I order crucibles in custom capacities or with lids and accessories?

A: Crucibles are available in capacities from 5 ml to 2000 ml. Custom sizes, lids, or other accessories can be requested at the time of ordering to suit specific experimental or process requirements.
