Design Features

Small silicon nitride ceramic crucibles (also known as laboratory melting crucibles) are designed for laboratory and high-temperature 

industrial applications for melting and chemical experiments. The superior physical and thermal properties of silicon nitride (Si3N4) 

make it ideal for handling high-temperature materials.

High Temperature Performance

Silicon nitride materials can withstand temperatures up to 1200°C. Their high thermal stability and heat resistance ensure reliable use 

under extreme conditions.

Corrosion Resistance

Silicon nitride exhibits extremely high resistance to a variety of chemicals, making it suitable for handling various chemical reactions, 

including those involving acids and alkalis.

Thermal Shock Resistance

It possesses extremely high thermal shock resistance (ΔT°C = 500), capable of withstanding rapid temperature changes without 

cracking or damage.

Structural Design

Crucibles are typically designed with a central hole and other shapes to accommodate specific assembly requirements, increasing 

versatility and improving experimental flexibility.

Physical Strength

High flexural strength (600 MPa) and compressive strength (2500 MPa) ensure that it maintains its shape and function under 

physical loads.

Application areas

Laboratory Research: 

Widely used in university and research institution chemistry and physics laboratories for high-temperature chemical analysis and 

materials science experiments.

Industrial Melting:

 Used in the metal processing and ceramics manufacturing industries for melting metals and other high-melting-point materials.

High-Temperature Furnace Applications: 

Used in high-temperature furnaces as melting vessels for processing materials such as glass or special alloys.
