NanOxideTM HPB-1000<100nm Barium Titanate
TPL’s NanOxide™ is a chemically precipitated high purity barium titanate designed to meet avariety of demanding electronics applications. HPB-1000 has an extremely tight particle size
distribution and is the smallest commercially available barium titanate on the market.
It is recommended for dielectric applications in the form of ceramic tapes, monolithic capacitors,
and composites.

Applications
HPB-1000 is finding use in multilayer multi-layer ceramic capacitors (MLCC), monolithic ceramic
capacitors, polymer-ceramic composites, electrode pastes and piezoelectric devices

Processing
When introducing HPB-1000 into your process, please keep the following points in mind:•••

The manufacturing process for barium titanate includes a drying step which induces soft
agglomeration (roughly 75 micron size particles). These agglomerates are easily broken up by
ultrasonication or ball milling.
Some harder agglomerates will also exist in the powder comprising several to tens of particles.
Because of the extremely fine particle size, these agglomerates require more energy than istraditionally required for larger, micron sized particles. In other words, when switching frommicron sized powder to nano-sized powder it may be necessary to lengthen ball milling timeby a factor of two or three.
Because of the extremely high surface area, higher surfactant concentrations are typicallynecessary to disperse nano-sized barium titanate relative to micron sized powder.

TPL, Inc. markets a formulated dispersing agent, NanoSperse™ 484, specifically designed toenhance dispersion of NanOxide™ ceramic powders in both aqueous and organic solvents.
TPL, Inc. has considerable experience with slurry production, tape cast compositions, composite
formulations, dry pressing and firing operations. We are happy to assist you in determining aprocess for your application.
