Body chemistry
Silica, alumina, fluxes, iron and loss on ignition are interpreted as a body system rather than separate supplier values.
Silica application consulting
Silica and industrial minerals consulting for ceramics
Ceramic bodies depend on the interaction of several minerals. Chemistry, whiteness, particle size, plasticity and firing behaviour must be considered together when qualifying a source or changing a blend.

02Firing response
03Particle preparation
Specification lens
What must be controlled
The target is not simply “high silica.” The useful specification is the combination of mineral, process and end-use behaviour that the customer actually needs.
Firing response
Fired colour, shrinkage, absorption and defect behaviour determine practical suitability.
Particle preparation
Residue, grindability and distribution influence milling energy, slip behaviour and body packing.
Blend stability
Silica, feldspar and clay variability is managed through source control and blending rules.
Process architecture
Indicative equipment train
Mineral approval should follow body and firing trials. Chemistry alone cannot predict ceramic performance.
- 01
Raw preparation
Crushing, screening, blunging or washing selected for the mineral and process route
- 02
Impurity control
Magnetic separation and controlled handling for iron and foreign-material reduction
- 03
Size reduction
Ball mill or dry grinding circuit with residue and energy targets
- 04
Solid-liquid handling
Hydrocyclones, filter press or spray drying where the ceramic process requires them
- 05
Blending & storage
Homogenizing bins, controlled dosing and lot-based quality release
Consulting approach
A decision path for ceramics and tiles
Technical guidance for silica, feldspar, ball clay and related mineral inputs used in ceramic and tile manufacturing.
Technical cautionMineral approval should follow body and firing trials. Chemistry alone cannot predict ceramic performance.
- 01
Review the complete body
Assess how the proposed mineral changes interact with clay, feldspar, silica and additives.
- 02
Compare unfired and fired behaviour
Laboratory trials connect raw-material values to shrinkage, absorption, colour and defects.
- 03
Adapt the preparation route
Set crushing, grinding, separation and blending duties around plant constraints.
- 04
Control supplier variation
Create incoming checks, blend limits and escalation rules for stable production.
Intended outcome
Mineral inputs selected and controlled for stable ceramic processing and finished-product quality.
Technical enquiry
Discuss your material and target specification
Share the source location, available test results, present process and required application. The first discussion will identify the questions that need evidence.
