Products

The manufacture of our refractory products comprises – depending on the product line – different methods of shaping, such as tamping, pressing (including isostatic pressing), slip casting and vibration shaping.


Magnesiasteine

Magnesite Bricks

Synthetic magnesite sinters, low in iron and boron, are used as raw materials for magnesite brick production. Their categorization is based on the CaO/SiO₂ ratio. Their excellent resistance against numerous basic ...read more

Magnesiazirkonsteine

Magnesia Zirconium Bricks

A special magnesite sinter with a controlled addition of  zirconium (ZrO₂ - SiO₂) are raw materials for these bricks. When fired, zirconium reacts with MgO by building a special matrix structure. The brick type is ...read more

Spinellsteine

Spinel Bricks

Spinel bricks contain more than 20 % and less than 40 % MgO depending on their classification.  The products that are fired at very high temperatures have a mineral content primarily of spinel (MgO - Al₂O₃). ...read more

Silikasteine

Silica Bricks

Silica bricks consist of > 90 percent by weight of SiO₂. In general, the SiO₂ content is 95 to 97 weight -%. Silica products are divided into dense and light. Depending on the requirements and demands they find ...read more

Schamottesteine

Fireclay Bricks

The predominant chemical components of fireclay products are SiO₂ and Al₂O₃. Fireclay products are categorized by their Al₂O₃ content which lies between 10 % and 45 %, by the choice of shaping (plastically, half ...read more

Tonerdereiche Steine

High-Alumina Bricks

P-D Refractories manufactures high-alumina bricks with an Al₂O₃ content range of 45 % to about 99 % and based on natural raw material sources and synthetic raw materials such as: Fused alumina and sintered ...read more

Basische Steine

Basic Bricks

Basic i.e. alkaline product brands have MgO as their dominating chemical material.read more

Zirkonsteine

Zirconium Bricks

Materials with a zirconium content are categorized in pure zirconium silicate materials and compounds of zirconium, mullite and corundum (aluminum-zirconium-silica material). Of note is that partly or fully ...read more

Chromsteine

Chromium Bricks

Chromium oxide bricks and chromium corundum bricks are part of chrome containing products. Chromium oxide is extracted through the elaborate processing of chromium ores, in contrary to all natural raw material. ...read more

Isostatisch gepresste Steine

Isostatically Pressed Bricks

Isostatic pressing  provides a very good homogeneous and solid, i.e. strongly densified,  brick structure due to the even compression during the manufacturing process. The shaping technologies normally used in the ...read more

Quarzgutsteine

Fused Silica Bricks

The basic raw materials for these products are silica glass (also called quartz), and glassy set SiO₂, which is manufactured by electric melting of high quality quartz sands (> 99,5 SiO₂).Shaping of the fused silica ...read more

SiC-Siliziumkarbid-Steine

Silicon Carbide Bricks

SiC products are based on synthetically manufactured silicon carbide grains with selected bonding components and metal oxide additives tuned to the use. The excellent characteristics of SiC products, such as high ...read more

Isoliersteine

Lightweight Insulation Bricks

Basic raw materials for insulating and lightweight refractory bricks with an overall porosity of > 45 % are porous materials, such as diatomite, vermiculite, hollow sphere corundum or -ash with different alumina ...read more

Cordieritsteine

Cordierite Bricks

The basic raw materals for cordierite products are cordierite fireclay and special MgO-substrates which contribute to the cordierite formation at the point of an Al₂O₃ and SiO₂ surplus, in particular in the bonding ...read more

Magnetit-Wärmespeichersteine

Magnetite Storage Heater Bricks

Magnetite bricks are used as storage heaters and made on the basis of selected magnetite raw materials on modern hydraulic presses.read more
