Description

Barium Strontium Titanium Oxide is a high-performance, multi-component ceramic precursor material. This compound matters for its exceptional dielectric and ferroelectric properties, which are critical for advanced electronic applications. It is primarily needed by manufacturers in the electronics, telecommunications, and advanced materials sectors for producing multilayer ceramic capacitors (MLCCs), sensors, and non-volatile memory devices.

Application

• Key dielectric material for Multilayer Ceramic Capacitors (MLCCs) in consumer electronics and automotive systems.
• Fabrication of pyroelectric and piezoelectric sensors for infrared detection and pressure measurement.
• Core component in tunable microwave devices and phase shifters for telecommunications infrastructure.
• Precursor for thin-film ferroelectric random-access memory (FeRAM) and other non-volatile memory technologies.
• Used in the synthesis of lead-free piezoelectric ceramics for environmentally friendly actuators and transducers.
• Research and development of electro-optic materials and advanced functional coatings.

Quality Control

Our Barium Strontium Titanium Oxide is produced under stringent quality management systems to ensure batch-to-batch consistency and performance reliability for critical electronic applications. Product quality is verified through advanced analytical techniques including X-ray diffraction (XRD) for phase purity, particle size analysis (PSA), and inductively coupled plasma (ICP) for elemental composition. Certificates of Analysis (COA) detailing all relevant specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed in a dry environment to prevent absorption of atmospheric moisture, which can affect performance.
