Silicon nitride ceramics provide excellent thermal shock, extreme thermal stress resistance, excellent wear resistance, and good chemical resistance. The main features are as follows:
1. High-temperature resistance, it can withstand high temperatures up to 1000ºC
2. Precision machining is possible, with a tolerance of up to 0.001mm
3. High-temperature chemical corrosion resistance, except HF and H3PO4
4. Extremely strong wear resistance
5. Excellent mechanical properties, hardness, compression, and bending strength are much higher than stainless steel
Si3N4 material is widely used as a thermocouple protection tube, has a long service life, and is maintenance-free.
As a necessary means of measuring temperature, a thermocouple protection tube is suitable for metallurgical industries, such as aluminum, tin, lead, zinc, and so on. The advantages are:
-Si3N4 material has better thermal shock resistance and high-temperature mechanical strength, light, high strength, and easy operation. It will not burst even if it is exchanged during processing, which is convenient for production and maintenance.
-Si3N4 material has the advantage of low conductivity. Its low specific heat can minimize heat loss. This will facilitate the temperature measurement accuracy of the thermocouple protection tube.
-The low wettability of aluminum liquid prevents slag from sticking inside the tube, so it is easy to maintain and operate.
-Si3N4 has excellent corrosion resistance and wear resistance and ensures a longer working life. If properly maintained, the actual service life can reach 2-3 years.
Edgetech supplies a large number of silicon nitride ceramic products, including Si3N4 ceramic tubes, Si3N4 ceramic plates, Si3N4 ceramic rods, and various complex ceramic structural parts.
