Ceramics Industry Overviewb sections covered

Sub-sectors coveredRefractoriesAdvanced / engineering ceramicsBuilding ProductsWhitewares

Diverse applications within one industry leading to equally diverse requirements in some cases.

Some areas thermal measurements vital, other areas very little requirement.

Ceramics Industry Refractories

Temperature range – Ambient - 1600C

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
