Products purpose
It mainly used for the heating elements of high temperature box resistance, tube furnace, vacuum furnace, hot-pressing furnace, sintering furnace, etc. It can work under oxidizing atmosphere, vacuum condition, inert gas conditions and reducing condition.
Major element and performance
Zirconium diboride composite ceramic heating element is a kind of composite ceramic materials which with zirconium diboride for main ingredients. | |
Melting point of Zirconium diboride | 3040°C, black solid |
Density | 5.8g/m3 |
Resistivity | 5.6×10-5Ω.m solid |
Technology Features
Maximum surface temperature under oxidation atmosphere | 2050°C |
long-term working temperature range under oxidation atmosphere | 100-1900°C |
Maximum surface temperature under vacuum, inert gas and reducing conditions | 2600°C |
Long-term working temperature vacuum, inert gas and reducing conditions | 2200°C |
Heating-rate fast speed, it can reach 1900°C within 120 minutes. | |
With good resistance to heat shock effect, can be applied for the thermal shock resistance test of ultra-high temperature material. The heating element is stable and reliable, long service life and lower maintenance costs. | |
Strong anti-corrosion resistance, it can work under poor conditions | |
Small power, easy to install. | |
