Knowledge of dimensional changes with respect to time and temperature is vitally important in many engineering problems. Examples range from quality control of sintering processes to materials selection and design, failure analysis and composites research. The dilatometer is the standard tool used to directly investigate dilation and contraction upon heating and/or cooling.
A number of processing steps in ceramic manufacturing result in the emission of hazardous air pollutants (HAPs) such as acid gases (e.g., hydrofluoric acid, HF; and hydrochloric acid, HCl) that are released in the high-temperature firing steps of the manufacturing process.
Our June issue includes features focusing on ceramic medical/dental applications, building-integrated photovoltaics challenges and opportunities, analytical challenges, and the new OSHA silica rule. Check it out today!
