Sol-Gel and Ceramic Precursors
Application & material guidance
Sol-Gel and Ceramic Precursors
The precursor route connects liquid chemistry to ceramic fibers, powders and matrices. Morlion’s development offering spans ceramic sols, fine powders and dispersions.
Control the starting chemistry
Oxide composition, solids content, pH and viscosity influence spinning, coating and infiltration. Subsequent drying and heat treatment determine ceramic conversion and phase development. Mullite, alumina, silica and zirconia sols address different formulation requirements.
Link powder and slurry properties to processing
Particle size, dispersion stability and solids loading influence coating quality and forming behavior. Sintering conditions and sample preparation must accompany density and strength data so that results can be reproduced and compared.
Define the development variables
- Target oxide phase, purity and impurity limits.
- Process viscosity and measurement method.
- Drying, debinding and firing schedule.
- Required density, porosity and dimensional stability.
High-solids formulation development
A Chinese-site article describes Guozhuang-developed mullite sols above 55 wt.% solids and alumina sols above 50 wt.% solids, both with viscosity below 50 mPa·s. These are separate development formulations, not replacements for the Z200-40 and AS-20 brochure values. Ask for the exact formulation, measurement temperature and current supply sheet when discussing coating or infiltration trials.
