ABSCO Materials supplies high purity zirconium oxide powders which are produced by chemical precipitation of high purity zirconium precursor chemicals such as zirconium hydroxide and zirconium carbonate.  The precipitation stage in the process determines a number of physical characteristics of the powder such as particle size and morphology.

Calcination of the precipitate in a tunnel or box kiln produces a zirconium oxide agglomerated powder.  The temperature and length of calcination control parameters such as the surface area of the powder.  The surface area and morphology of a powder affects its reactivity, an important characteristic for many applications.

The final stage is jet milling or wet milling which breaks down the agglomerated material and also reduces the particle size if a fine powder is required.

ABSCO Materials is able to offer a range of particle sizes and surface areas and can also meet individual customer requirements.

These high purity zirconium oxide powders are used in structural ceramics, electro ceramics and thermal barrier coatings.

 

ABSCO Materials supplies a range of fused and crushed powders which are produced by the direct fusion of zircon sand in an arc furnace.  The fused zirconium oxide is then milled to various particle size ranges depending on the application.

ABSCO Materials is able to offer a range of mesh sizes or fine particle sizes and can meet individual customer requirements.

The fused zirconium oxide powders are used in refractories, structural ceramics, thermal barrier coatings and ceramics pigments.

Zirconium oxide has excellent resitance to molten metal erosion and is extremely refractory and chemically inert in most environments.  Zirconium oxide refractories tend to be used in applications where temperatures are in excess of 1,900 degrees C, such as in continuous casting nozzles, crucibles, kiln furniture and furnace liners.  The use of zirconia is growning in line with the trend towards more specialised refractories.

 

ABSCO Materials supplies a range of yttria stablised zirconium oxide powders which are produced by the co-precipitation of yttrium oxide and zirconium oxide from high purity precursor chemicals.

Calcination of the precipitate in a tunnel or box kiln produces an yttria stabilised zirconium oxide agglomerated powder.  The temperature and length of calcination controls parameters such as surface area of the powder.

The final stage is jet milling or wet milling which breaks down the agglomerated material and also reduces the particle size further if a fine powder is required.

ABSCO Materials offers a range of powders with different levels of yttrium oxide dopant, hence different levels of stabilisation.

Granulated, ready to press, powders are available for use in the production of pressed and sintered structural ceramics.  These free flowing doped zirconium oxide powders produce less dense ceramic components for high performance applications.

Yttria stabilised zirconia (3mol% YTZP) is predominantly tetragonal in structure and has the highest flexural strength of all the zirconia based materials, particularly when HIPed.  The fine grain size of yttria stabilised zirconia lends itself to be used in cutting tools where a very sharp edge can be achieved and maintained owing to its high wear resistance.

The fine grain size leads to a very dense, non porous ceramic with excellent mechanical strength, corrosion resistance, impact toughness, thermal shock resistance and very low thermal conductivity.

Agglomerated and sintered zirconium oxide powders are also available for thermal barrier coating applications.

Yttria stabilised zirconium oxide is used as the ceramic topcoat in thermal barrier coatings owing to its very low thermal conductivity.  This layer creates the largest thermal gradient of the thermal barrier coating and keeps the lower layer metal substrate at a lower temperature then the surface.  These coatings are used on aerospace and land based gas turbine blades and improve the life and performance of the turbine.

The fused calcia stabilised zirconium oxide powders are used in refractories, structural ceramics and investment casting.

Zirconium oxide has excellent resistance to molten metal erosion and is extremely refractory and chemically inert in most environments.  Stabilised zirconia refractories exhibit low thermal conductivity resulting in very low heat loss.  Zriconium oxide refractories tend to be used in applications where temperatures are in excess of 1900 degrees C, such as in continuous casting nozzles, crucibles, kiln furniture and furnace liners.  The use of zirconia is growing in line with the trend towards more specialised refractories.

 

ABSCO Materials supplies a magnesia stabilised zirconium oxide powder which is produced by the co-precipitation of magnesium oxide and zirconium oxide from high purity precursor chemicals.

Calcination of the precipitate in a tunnel or box kiln produces a magnesia stabilised zirconium oxide agglomerated powder.  The temperature and length of calcination controls parameters such as the surface area of the powder.

The final stage is jet milling or wet milling which breaks down the agglomerated materials and reduces the particle size further if this is what is required.

ABSCO Materials offers magnesia stablised zirconium powder as a fine powder or a granular, ready to press, powder for producing pressed and sintered ceramic components.

Magnesia stabilised zirconium oxide has a cubic phase which is loaded with tiny tetragonal phase precipitates, giving a very high level of transformation toughness.  Magnesia stabilised zirconium oxide is able to give the highest level of fracture toughness.

Magnesia stabilised zirconium oxide has excellent mechanical properties, including high strength, fracture toughness, wear resistance, good thermal shock and low thermal conductivity.  Due to these characteristics it finds use in high wear and corrosion applications including valves, pumps and liners.  It is the material of choice for the chemical processing and petrochemical industries.

ABSCO Materials supplies a high purity zirconium oxychloride produced by an alkali fusion of zircon sand followed by dissolution and separation.

Zirconium oxychloride is used in its own capacity in applications such as the production of titanium dioxide pigments but it is more often converted to other zirconium chemicals and oxides.

 

ABSCO Materials supplies a high purity zirconium basic sulphate produced by the precipitation of zirconium oxychloride.

Zirconium basic sulphate is used in applications such as leather tanning and titanium dioxide pigments but it is also often converted to other zirconium chemicals and oxides.

 

Zirconium basic carbonate is perhaps the most important zirconium chemical as it is often the pre-cursor material for many zirconium products.

ABSCO Materials supplies a number of high performing zirconium basic carbonate pastes, produced by the precipitation of zirconium basic sulphate.  Through careful process control, high purity and reactive pastes are produced which are suitable for the production of a range of zirconium based chemicals used in catalysis, paper coating and paint dryers to name a few.

ABSCO Materials offers a high purity grade used in catalysis and also a reactive grade for use in the production of paint dryers.
