Ceramic coated molybdenum sheets / plates

Molybdenum sheets / plates with welding prevention effect during firing

Do you have the problem of stuck or reaction during singtering process?
Our unique ceramic coated molybdenum plate not only prevents workpiece from stuck but also provides various advantages.
If you conventionally use ceramic plates, you will be able to shorten furnace cycle time, increase charge of parts, and enhance accuracy of burned material. If you use molybdenum plates without coating, stuck will be prevented and the ceramic plate will become unnecessary. Coating composition can be selected according to sintering product; in addition, it can be coated not only to plates but also to boats and other processed products.

Characteristics
Ceramic plate × × × Takes time to raise/lower the temperature; plate thickness is thick, so the charge amount is small; short life of the board; deformation of the burned material.
Molybdenum plate (w/o coating) × Use with a ceramic board is required to prevent welding.
Ceramic coated molybdenum plate While preventing welding, increased charge and shortened temperature rise/fall time may occur.

If you conventionally use ceramic plates, shortened furnace cycle time, increased charge, and enhanced accuracy of burned material will be achieved; If you conventionally use molybdenum plates without coating, welding will be prevented.
