Thermal Analysis of Mineral Fibres DSC and TGA
topic
Differential scanning calorimetry of mineral fibres measures glass transition temperature, devitrification exotherm, and melting point as functions of composition, while thermogravimetric analysis quantifies mass change from sizing burnoff, moisture evolution, and fibre oxidation under controlled atmosphere from ambient to 1200 degrees Celsius at defined heating rates in nitrogen and air atmospheres.
Role
Characterises the thermal stability limits and transformation temperatures of mineral fibres that govern their maximum service temperature, guides selection of heat treatment conditions for ceramic fibre annealing and carbon fibre graphitisation, and quantifies sizing content for quality control of fibre surface treatment application uniformity.
