Advantages of Alumina Laboratory Crucible
Alumina laboratory crucible can withstand extremely high temperature environments, providing a solid guarantee for the smooth progress of experiments.
Alumina laboratory crucible have good corrosion resistance to most acids, alkalis, and other chemical reagents.
Alumina laboratory crucible do not release harmful impurities or gases at high temperatures, and have minimal pollution to experimental samples.
Application of Alumina Laboratory Crucible
In metallurgical experiments, it is necessary to heat the metal to a high temperature of over 1000 ℃ for melting and purification operations. Alumina laboratory crucible are fully capable of meeting such high temperature requirements, ensuring that the metal is uniformly heated inside the crucible and does not react with the crucible material.
When conducting ore composition analysis, it is necessary to use strong acid to digest the ore. At this time, the alumina laboratory crucible can withstand the corrosion of strong acid well and will not introduce additional impurities to interfere with the analysis results.
In crystal growth experiments, a uniform heating environment is crucial for the quality and growth morphology of crystals. Alumina laboratory crucible can effectively meet this requirement and help researchers obtain high-quality crystal samples.

Factory Equipment
Slip casting moulding: Inject the prepared slurry into the gypsum mold and let it stand for a period of time to allow the gypsum mold to absorb moisture. The slurry forms a uniform body on the inner wall of the mold.
Injection moulding: Inject a slurry containing paraffin into a metal mold at a certain temperature and pressure, and after the body cools and solidifies, perform demolding to prepare ceramic bodies.
Extrusion moulding: Suitable for long tube products, the powder is extruded into shape through an extruder.
