Low temperature sintering: hydro/solvothermal sintering process

APPLICATIONS

Low temperature process assisted by pressure under liquid phase (hydro/solvothermal reaction) suitable for technical ceramic making or multimaterials assembly (ceramic-ceramic or metal-ceramic).

This process allows to produce materials with a large scale of compactness
and porosity customisation (from <50% to ≥95%).

• A wide range of applications with a high market growth 6,5% of CAGR* for technical ceramic

*CAGR: compound annual growth rate

DESCRIPTION

Low temperature hydrothermal sintering process for technical ceramic making and multimaterials assembly

• Appropriate for a wide range of ceramics: oxide, sulfate, carbonate, phosphate, silicate, non oxide
• Ceramics and/or metals can be crystallized or amorphous
• Suitable for materials subject to transition at low temperature or metastable ones or nanometric materials
• Suitable for multimaterial assembly without interphase creation
• Low temperature and pressure process (from 25°C to 500°C and from 50 to 350MPa)
• Sintering duration : from 1 to 60 min

BENEFITS

Quantitative benefits

• Energy and cost efficency of the process
• Environment friendly process (no waste and green solvent)
• Heating process independent from material conductivity
• No need for a conductive mould nor a binder

Qualitative benefits

• New advanced ceramics or assemblies
• High flexibility for sintering criteria (temperature, pressure, material, solvent, duration…)
• Same high performance of the ceramics than the classical ones (light, resilient, corrosion or shock resistant, …)
