Can we use plate corundum make crucible?
yes.
Crucibles can use tabular corundum as a material.
Plate corundum has high hardness and wear resistance, and is suitable for making refractory materials such as crucibles. In addition, perform well at high temperatures, can withstand high temperatures without being easily deformed, and are suitable for various high-temperature experiments and melting processes.
Characteristics and applications:
High temperature resistance: can withstand high temperatures without being easily deformed, and are suitable for various high-temperature experiments and melting processes.
Wear resistance: Due to its high hardness, have good wear resistance and can maintain a stable shape during long-term use.
Corrosion resistance: have good corrosion resistance to a variety of chemical substances and are suitable for a variety of chemical experiments and melting processes.
Scope of application: Suitable for experiments such as melting NaCl, but not suitable for melting samples of alkaline substances and acidic substances such as Na2O2 and NaOH.
Description for plate corundum:
Tabular corundum is heat resistant and has good bulking temperature. A clear vibrating plate shape to increase the mechanical strength of the particles. The internal structure is closed pores; high bulk density; Significantly lower permeability and reduced water absorption capacity to reduce the amount of fluid recycling; Good physical properties such as: high refractoriness; Excellent heat resistance; With low shrinkage and good heat resistance. Meanwhile, Avoid damage to high purity machines.
