TPL offers a range of titanate powders with controlled size and chemistry. NanOxide™ powders are produced via an aqueous, low temperature process that allows for binary and tertiary oxide compositions with controlled
stoichiometries. The crystalline ceramic powders have uniform spherical
morphology and high dielectric constant with sintering temperatures as
low as 1000° C. Various dopants can be used with binary compositions to
modify properties for a wide range of ferroelectric applications. The
ultra-fine particle size makes the powders ideal for thin ceramic
capacitor layers and embedded polymer/ ceramic laminates.
Key Features of High Purity Barium/Strontium Titanate
Solid
solution compositions are fully adjustable to any ratio, from 1% to 99%
strontium. Similarly, the primary particle size can be adjusted for the
application, typically in the range of 50 nm to 500 nm. As such,
barium/ strontium titanate formulations are considered a specialty
product and are manufactured upon request. The dielectric constant on the barium/strontium titanate is typically between 10,000 and 15,000. TPL’s Barium Strontium titanate thin films and
composites are finding application into a wide range of broadband RF and
microwave devices such as tunable filters, phase shift devices,
electromagnetic absorbers and antennas.
Custom Formulations of Barium Strontium Titanate Ceramic Powders
TPL is dedicated to customer satisfaction and values the
necessity of custom formulations in a variety of manufacturing products.
TPL’s unique manufacturing process allows tremendous flexibility in the
production of ceramic titanates. As with the HSB, mixed metal titanate
formulations can be produced with a wide range of compositions. In
addition the particle size of the powder can be varied from 50 nm to
1,000 nm.
TPL’s
versatile manufacturing also means that a wide variety of dopants can
be added to any ceramic titanate over a range of concentrations. Dopants
can be added homogeneously
and heterogeneously to our ceramic titanates. Homogeneous additions
yield solid solutions while heterogeneous additions are designed to
yield core/shell structures to MLCC applications. TPL encourages
requests for chemical formulations that will meet customer
specifications.
When introducing NanOxide™ ceramic powders 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 is traditionally required for larger, micron sized particles. In other words, when switching from micron sized powder to nano-sized powder it may be necessary to lengthen milling time.
-
Because of the extremely high surface area, higher surfactant concentrations are typically necessary to disperse nano-sized barium titanate relative to micron sized powder.
TPL’s
titanate powders are readily dispersible in aqueous and non-aqueous
solvents with their formulated dispersing agent, NanoSperse 484,
specifically designed to enhance 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
and can assist in determining a process for your application.
