    1. EVITherMCeramics and Glass Industries Sarah Baxendale EVITherM 17/5/04

    2. Ceramics Industry Overview • b sections covered • Sub-sectors covered • Refractories • Advanced / engineering ceramics • Building Products • Whitewares • Diverse applications within one industry leading to equally diverse requirements in some cases. • Some areas thermal measurements vital, other areas very little requirement.

    3. Ceramics Industry Refractories • Temperature range– Ambient - 1600C • Thermal Property Data • Thermal conductivity • Data for heat transfer calculations • Data for finite element analysis – eg texp, tcond, thermomechanical props, emissivity, specific heat • Training requirements • Measurement of thermal conductivity, expansivity, emissivity and specific heat. • Heat calculations • Shortening of firing schedules • Measurement of temperature • Control of temperature • Most important offering of an internet site • Ready access to thermal data • Best practice guide for heat transfer coefficient predictions
