Materials Development


Innovarcilla Materials Area works for / with companies in both comprehensive R & D + I projects and in the support and advice for the development of new materials, from the following range of technological services:

  • Design of materials and ceramic pastes based on previous specifications from the existing production process or functional and/or appearance requirements for the final product.
  • Material or energy recovery of industrial wastes and by-products in the ceramic sector.
  • Development of alkali activated materials according to applications.
  • Functional surface applications.
  • Development of materials for different applications according to the main shaping technologies.
  • Controlled porosity materials for filtration applications, functional supports (catalyst) or thermal insulation improvement.
  • Materials with high thermal inertia.


In addition to the subjects described above related to the design and development of new materials for different applications, Innovarcilla offers the following services related to materials characterization and laboratory analysis:

  • Physical characterization of materials:
    • Determination of real and apparent density of materials
    • Particle size analysis by X-ray absorption, by dry-sieving and by wet sieving

    • BET specific surface.
  • Ceramic Processing:
    • Preparation of samples for technological characterizations (reception humidity, crushing, dry or wet milling, ball milling, pendular mill, atomization)
    • Forming material by extrusion or pressing. Compaction diagram of ceramic powders at fixed humidity and three pressure values. Other methods of forming (slip casting)
    • Characterization of dry samples: working moisture (extrusion) or post-pressing expansion (pressing), drying shrinkage, Bigot curve (extrusion), cracking limits (extrusion), bulk density and flexural strength, tempering moisture and resistance loss during tempering.
    • Characterization of fired samples: Firing in electric or propane kiln (up to 1700 ° C), weight loss and linear firing shrinkage, bulk density, water absorption, mechanical strength, colour and chromaticity coordinates, evaluation of efflorescence and pyroplastic deformation.
