Founded 1957
Head Office Mosonmagyarovar, Hungary
Major Products

Production of electroformed bricks

Electroformed bricks are made by electrically melting ceramics (alumina + silica + zirconia) at a high temperature of 1,800℃ or higher, pouring them into a mold (made of silica sand or carbon) and then cooling before processing them into desired shape.
These electroformed bricks made of various crystals are very dense (relative density >95%) leading to excellent erosion resistance to molten glass and are thus indispensable for glass melting furnaces.

P-D DYKO (Germany)

DYKO-GLASS P-D refractories Lito GmbH
Company Name DYKO-GLASS P-D Refractories Lito GmbH
Head Office Düsseldorf, Germany
Major Products

Manufacturer of dense zircon, dense chrome

Dense sintered bricks are manufactured by a unique method. Ordinary bricks are fired at high temperature after compression molding resulting in a porous low density material making erosion by molten glass a problem.
In contrast, P-D DYKO's dense sintered bricks are dense and reliable as they are manufactured by advanced technology using the rubber press method to achieve uniformity under high pressure. Although electroformed bricks are dense, they are weak against heat shocks and are inferior regarding electrical insulation. Dense zircon overcomes these problems and has been widely used in melting furnaces for LCD-glass in recent years.
Dense chrome bricks excelling in erosion resistance are used in the throat of bottle glass furnaces, the corner of the doghouse, and fiber glass furnaces.
