P-D DYKOミ
P-D DYKO (Germany) http://www.pd-gruppe.de/
Company name: P-D Refractories GmbH | DYKO-GLASS
Location of headquarter: Düsseldorf (Germany)

Technology:
Dense Zircon and dense Cr2O3 refractories. These refractories are specially produced by rubber pressed method,
which are pressed in the liquid by equivalent pressing. After the pressing, they are fired in the kiln. Compared to fuzed cast refractories,
these dense blocks are more stable against thermal shock and higher electrical resistance. By these properties, they are suitable materials for LCD and fiber glass production.
Especially the dense Cr2O3 has strong properties against chemical corrosion and is used for the throat and dog-house corner blocks of container glass furnaces.
