TPL offers a range of titanate powders with controlled size and chemistry. The nano-size ceramic powders are produced via an aqueous, low temperature process that allows for binary and tertiary oxide compositions with controlled stoichiometries. (Standard compositions include barium and strontium titanate.) The ultra-fine particle size, 50 to 400 nanometers (nm) of these ceramic powders make them ideal for ultra-thin dielectric layers in composites and ceramic capacitors. TPL has the ability to provide ceramic nano-powder formulations to customer specifications.
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.
TPL’s titanate powders offer high purity, nanometer size and are designed to meet demanding electronics applications. Our titanate powders have been successfully used in multilayer ceramic capacitors (MLCC), monolithic ceramic capacitors, ceramic tapes, polymer composites, polymer-ceramic composites, electrode pastes and piezoelectric devices. 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.
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.

Barium Titanate powders are crystallographically cubic, phase pure barium titanate. It is suitable for use in formulating X7R compositions for air fire and reducing atmospheres. In addition, base metal electrode compositions may also be developed. TPL, Inc. has worked with numerous companies to develop and manufacture compositions tailored to their processes. The formulations developed for those customers are proprietary; therefore, TPL, Inc. can not sell these formulations to outside users. TPL is happy to work with all customers who can provide a desired composition. We are capable of doping barium titanate both homogeneously and heterogeneously to yield either, or both, solid solutions or core/shell compositions.
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.
