Lactic Acid Content

Fused silica micro-powders with D50of 1.8μm were firstly prepared by ball milling. Effects of milling time on particle size distribution and microstructures of the powders were discussed. Then, the green compacts with volume density of 1.86g/cm3was obtained by slip casting with lactic acid as dispersant. Effects of lactic acid content on apparent viscosity of the slurry, thickness and density of the green compacts were investigated. Finally, fused silica ceramics with thermal expansion coefficient of 0.56∙10-6/°C, bending strength of 64MPa and volume density of 1.94g/cm3were prepared.

The thermal expansion of ceraptic materials has become a property of interest to more people recently since the desirability of a thermally stable space platform was recognized. The interest in low thermal expansion materials in the past has been driven mildly by the recognition that low thermal expansion will foster good thermal shock resistance. The tradition of the ceramics industry for nearly one hundred years has been that zircon and cordierite were the low expanding materials. Fused silica has long been recognized for its low expansion. But when in 1947 Hummel (1957, I960) found ultra-low-expanding bodies in the lithium aluminum silicates with spodumene and later β-eucryptite structures, a new kind of phenomena had been introduced. Roy (1949), Roy, Roy and Osborn (1950) and Roy and Osborn (1959) provided much of the crystal chemical and phase diagram background on this family.
