Ceramic coated molybdenum sheets / plates
Molybdenum sheets with anti-welding effect during firing
Do you have trouble with welding and reaction during the firing process?
Using our proprietary ceramic-coated molybdenum sheet offers various advantages. Customers currently using uncoated molybdenum sheets can reduce adhesion to the furnace by switching to this product. In addition, customers currently using ceramic plates can expect shorter furnace cycle times, higher component charge volume, and improved sintered product accuracy by switching to this product. In addition to the choice of coating compositions to match the fired product, the product can also be used to coat 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 quantity, and enhanced quality of burned material will be achieved; If you conventionally use molybdenum plates without coating, welding will be prevented.
