The microstructure of solder compositions based on high-lead low-melting glass and lead titanate as a crystalline filler correcting the temperature coefficient of linear expansion (TCLE) of solder has been studied by optical microscopy in combination with birefringence testing with a locality of about 1 µm. The influence of the specific surface area and filler concentration on the TCLE of sintered composites was studied in order to obtain composites with abnormally low TCLR values for solder materials. In composites containing up to 55 % PbTiO3 powder with a specific surface area of less than 560 cm2/g, near-zero and even negative values have been achieved.
