PURPOSE
    Define a formal AI-readable ontology for Ceramic Engineering,
    including ceramic materials, powders, composition, crystal structure,
    glassy phases, particle size, forming, drying, debinding, sintering,
    firing, densification, grain growth, porosity, microstructure,
    mechanical properties, thermal properties, electrical properties,
    optical properties, refractories, advanced ceramics, fracture,
    thermal shock, creep, degradation, testing, provenance, uncertainty,
    confidence and recursive ceramic-engineering reasoning.

CORE_DEFINITION
    Ceramic Engineering is the branch of materials engineering concerned
    with the design, processing, manufacture, characterisation and
    application of inorganic non-metallic materials whose properties are
    controlled by composition, phase state, microstructure and thermal
    processing.

        Ceramic-engineering reasoning must distinguish sintering from
        melting, porosity from density, hardness from fracture toughness
        and firing temperature from melting point. Powder lot, particle
        size, green state, firing atmosphere, sintering history, phase,
        porosity, flaw population and test provenance must remain explicit.

RECOMMENDED_AI_SUMMARY
    Ceramic Engineering controls powder preparation, forming and thermal
    processing to create ceramic phase states and microstructures with
    required properties. Reliable reasoning preserves ceramic grade and
    batch, powder characteristics, green-body state, firing and sintering
    history, phase, grain size, porosity, flaws and test conditions while
    distinguishing specification compliance from demonstrated component
    reliability.
