TPL, Inc.

Nano Composite Dielectrics TPL’s composite dielectric material represents a significant breakthrough in dielectric materials for high energy density capacitors. Efforts in this area have transitioned from materials development, supported by basic R & D contracts, to device fabrication for a number of pulsed power and directed energy applications. TPL has developed composite materials possessing a high dielectric constant (k>50) and forming capabilities of a polymer. The nano-composite dielectric can be molded into engineering substrates or cast into complex electrode structures for producing high voltage capacitive components. TPL has established processes for fabricating substrate dielectric and capacitors in a number of configurations including strip lines, rods, sheets and blocks.

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.

Key Features of High Purity BariumStrontium 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 bariumstrontium 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 coreshell structures to MLCC applications. TPL encourages requests for chemical formulations that will meet customer specifications.

TPL designs and produces specialty ceramic components using formulated titanate powder. Specialty parts, primarily for high voltage and high frequency applications, are produced to meet custom dimensions and electrical properties. TPL’s processes accommodate a range of capacitor and substrate geometries. In addition, powder formulations are tailored to achieve specific performance characteristics including dielectric constant, dielectric loss and insulation resistance.
