Conical Crucibles

Features of Conical Crucibles

1. Shape and Design:

   • Conical shape with a tapered body ensures easy pouring and handling of materials.

   •  Designed with a pointed or slightly rounded bottom to prevent spillage and facilitate easy collection of melted or processed materials.

2. High-Temperature Resistance:

   • Made from refractory materials like porcelain, alumina, graphite, or silica, making them highly resistant to high temperatures, typically ranging from 1000°C to over 1700°C.

3. Chemical Resistance:

   • Inert to most chemicals, including acids, alkalis, and solvents, making them ideal for chemical reactions and sample preparation in laboratories.

4. Durability:

   • Resistant to thermal shock, ensuring longevity even through repeated heating and cooling cycles.

   • Designed to withstand mechanical stresses encountered during handling or high-temperature processes.

5. Capacity Options:

   • Available in various sizes, ranging from small laboratory sizes (e.g., 10 ml to 100 ml) to larger industrial-scale crucibles for melting and processing materials.

6. Smooth Interior Surface:

   • The inner surface is typically smooth, minimizing the risk of sample contamination and making it easier to remove the contents after heating.

7. Versatile Applications:

   • Ideal for melting, calcining, ashing, or performing chemical reactions in laboratories, metallurgy, ceramics, and material science.

   • Suitable for use in furnaces, kilns, and Bunsen burners.

8. Enhanced Handling:

   • Often designed with flared edges to provide a better grip and minimize spillage when handling hot substances.

   • May be compatible with crucible tongs or holders for easy removal from heat sources.

9. Optional Lids:

   • Available with fitting lids to prevent contamination, oxidation, or evaporation of substances during heating.

10. Applications in Industry and Research:

    • Widely used in chemical analysis, metallurgy, ceramics, glassmaking, research labs, and material testing.
