Crucible Furnace

High Temperature Crucible Furnace up to 1200°C for Melting

Brother crucible furnace has unique ceramic fiber insulation around the chamber, the chamber can provide excellent uniformity temperature and energy efficiency. Its crucible is made of high-purity quartz. The heating element is embedded in the insulation for maximum heat transfer to the chamber. Max. temperature can reach 1200℃.

Crucible Furnace Application:

It is widely used in the field of ceramic, metallurgy, electronic, chemical, machinery, anti-fire material, new material development, special material, building material for calcining high purity compound under the condition of inert gas, also can be used for annealing or roasting and sintering ceramic material.

Crucible Furnace Features:

  • High purity quartz crucible
  • Designed for sintering ceramic parts, components, materials, etc.
  • Double layers steel casing with fan cooling, to ensure the surface of furnace below 50C.
  • Simple operation process through 30 segment PID control panel.
  • Integrated double circuit and alarm system make the furnace more safe, stable and reliable.
  • Better temperature uniformity and can be flowed into different inert gas or draw out to vacuum.
  • Vacuum optional.
