Texturing Polycrystalline Ceramics
>> Templated Grain Growth (TGG) is a low-cost ceramic processing
route to produce ceramics with single-crystal like properties.
>>Using shear forming methods, plate or needle particles can be
oriented in a matrix of fine ceramic powder. Matrix powders
are designed to provide the surface energy required for component
densification and template particle growth
>>During heat treatment, the template particles serve as nuclei for oriented
crystal growth, which consume the matrix and form a textured ceramic.
Sodium Niobate (NaNbO3) Barium Titanate (BaTiO3)
Template Materials
The key to successful TGG and textured ceramic product development are consistent, controlled and reproducible sources of template particles. Bench scale synthesis is slow, costly and labor intensive. Batch to batch variation in template synthesis conditions affects product purity, template size and aspect ratio.
We provide Entekno Barium Titanate and Sodium Niobate platelet template powders to teams looking to advance piezoelectric and dielectric textured ceramics. Activate also supplies complementary matrix powders for lead free piezoelectric and dielectric ceramics via TGG.
