Silica Ash Crucible SiO2 99%
Silica Ash Crucible SiO2 >99%
A Silica Ash Crucible with >99% SiO2 is used for high-temperature laboratory applications, including ash determination in coal testing, general heating and combustion, and volatile matter analysis. Its high silica content provides excellent thermal stability and resistance to high temperatures (above 1100 °C), making it ideal for controlled, high-temperature processes where precise measurement of residue is required.
Silica Ash Crucible SiO2 99% Specific Uses
Coal Ash Analysis:
The crucible's primary use is to hold pulverized coal samples for incineration in a muffle furnace to determine the ash percentage after burning the volatile matter.
Combustion and Heating:
It serves as a vessel for high-temperature applications, including the controlled combustion or evaporation of volatile materials in a laboratory setting.
Sample Analysis:
Researchers utilize these crucibles for analyzing samples, providing a stable, non-reactive environment for accurate measurements at high temperatures.
Volatile Matter Determination:
In processes like determining the volatile matter in coal, the crucible ensures that only the ash residue remains after a carefully controlled heating process.
Why a High-Silica Crucible is Used
High-Temperature Resistance:
A crucible made of >99% silica can withstand temperatures exceeding 1100 °C without significant deformation or chemical reaction.
Purity:
The high purity of the silica (SiO2) minimizes contamination of the sample during testing, which is crucial for accurate analytical results.
Controlled Reactions:
The inert nature of silica provides a stable and controlled environment for heating and combustion experiments, ensuring the integrity of the process and the sample.
