Alumina ceramic crucible

Alumina crucible, we usually called more than 95% alumina content crucible is corundum crucible.

It is composed of porous fused alumina, with the characteristics of strong and resistant to melting, suitable for the use of anhydrous Na2CO3 and other weak alkaline substances as flux molten samples.

Characteristics

Resistant to high temperature, acid and alkali, rapid cooling, rapid heat, chemical corrosion.

No sample change prior to measurement

The alumina crucibles can be used in combination with special Al lids. They prevent sample changes during the waiting period before the measurement. This is of high relevance for samples that can take up water or samples that evaporate content.

Regeneration of alumina crucibles

After mechanical cleaning store, if needed, in water (or even in 10% hydrochloric acid). Oxides may form which can then be removed by rinsing. After drying, heat the crucibles to red hot to ensure that no weight loss occurs when they are used.

Several metals are critical

Al2O3 has the tendency to form spinels with Fe2+, Ni2+, Cu2+ and others, particularly at temperatures above 1000 °C. In addition, the melt of these metals dissolve Al2O3.

Application

Sample preparation for spectroscopy: It can be used for preparing samples for spectroscopic analysis. These crucibles can withstand high temperatures and are chemically inert, making them ideal for heating and holding the samples during the analysis.
Melting and casting of metals and alloys: Used for melting and casting metals and alloys due to their high thermal conductivity and excellent resistance to high temperatures. These crucibles can be used in applications such as metalworking, casting, melting, and even jewelry making.
Chemical analysis: Used for heating and holding various chemical solutions and samples during chemical analysis.
Powder metallurgy: Used in powder metallurgy for sintering and muffle furnace applications. These crucibles can withstand high temperatures and are an ideal choice for processing and manufacturing metal powders and alloys.
Thermal analysis: Used in thermal analysis experiments for measuring the thermal properties of materials. These crucibles are perfect for holding and heating samples during the thermal analysis process.
Environmental analysis: Used in environmental analysis for heating and holding various environmental samples. These crucibles can withstand high temperatures and are chemically stable, making them an ideal choice for environmental sample analysis.
Pharmaceutical and biomedical applications: It can be used in pharmaceutical and biomedical applications such as manufacturing drugs and medical devices.

Storage

Should store it seal dry environment.
