Alumina ceramic crucible
VR

Ceramic Crucible Combustion Boat are manufactured by using premium quality ceramics. In metallurgical, glass and jewelry industry these boats are used for melting materials at high temperature.


Application
Made of 99.0% pure, recrystallized Alumina Combustion Boats for high resistance to chemical attack.
Alumina (Al2O3) has a wide application due to its versatility and low material cost. Alumina possesses a high melting point, strong hardness, and good chemical stability, making it a good material to withstand high temperature and chemical corrosion.


Suitable for all kinds of laboratory metal and nonmetal sample analysis and melting materials, firing and processing of material applied in laboratory and various industries,such as metallurgy, chemical industry, materials science and so on.


Ceramic Combustion Boats features:
1.Good thermal shock,no easy to crack.
2.Dimensionally accurate
3.Durable
4.Good corrosion resistance.
