Silicon nitride crucible

INTRODUCTION:

Silicon Nitride Crucible is a high-temperature resistant container made of advanced ceramic material silicon nitride (Si3N4),designed for melting, purification, and material processing in extreme environments. Its unique physical and chemical properties make it an irreplaceable core tool in semi-conductor manufacturing, photovoltaic industry, high-temperature alloy melting, precious metal processing, and scientific research laboratories, significantly improving process efficiency and product quality while reducing equipment losses and energy consumption costs.

FREATURES:

1.Ultra high temperature tolerance

The working temperature is above 1600 degree, and it can withstand an instantaneous high temperature of 1800 degree for a short period of time without softening, oxidation or deformation, ensuring the stability of the melting process.

2.Excellent thermal shock resistance

The extremely low thermal expansion coefficient combined with high thermal conductivity can resist rapid temperature changes (such as rapid temperature rise and fall) and avoid the risk of cracking.

3.Super resistant to chemical corrosion

It has excellent corrosion resistance to molten metals (aluminum, copper, gold, silver, etc.), acidic/alkaline molten salts, and semiconductor materials (silicon, gallium arsenide) to prevent pollution.

4.High purity and low pollution

The material is dense and pore free, avoiding the infiltration of impurities and ensuring the purity of the melted material (suitable for processing high-purity metals or semiconductors with a purity of over 99.999%).

5.Light weight and Long service life

The density is only 3.2g/cm3, which is lighter than traditional graphite or quartz crucibles; Excellent wear resistance, extending service life by 3-8 times and reducing overall costs.
