By California Nanotechnologies Corporation
California Nanotechnologies, based in Cerritos, California, is an industry-leading provider of advanced milling, sintering, and material development services. Leveraging state-of-the-art planetary ball milling capabilities, Cal Nano enables clients across aerospace, energy, healthcare, electronics, and advanced manufacturing to achieve nanoscale precision in powders and composites. Cal Nano has positioned itself as an expert in planetary ball milling services, offering: - Material pulverization into fine powders - Mechanical alloying to form nanostructured or metastable alloys - Solid-state chemical synthesis, enabling mechanochemical reactions without solvents - Composite blending and homogenization for nanocomposite fabrication They combine planetary milling with other advanced techniques such as cryomilling and Spark Plasma Sintering (SPS) to offer hybrid, tailored solutions. This technique offers several advantages that make it indispensable for aggressive and precise material processing: - Ultra-fine particle sizes: Capable of producing powders down to tens of nanometers. - Versatility: Suitable for hard, brittle, fibrous, or wet materials, and adaptable to both dry or wet milling modes. - Controlled reproducibility: Users can tailor milling conditions—time, speed, ball size, media—to achieve consistent, uniform outcomes. - Efficient mechanical energy input: Produces impact and shear forces ideal for alloying, mixing, synthesis, and size reduction. However, challenges include heat generation (which can affect heat-sensitive materials) and potential contamination from wear of grinding media if not carefully managed. Cal Nano addresses these through process controls and choice of media/geometries. Cal Nano’s planetary ball milling capabilities support a wide range of high-tech sectors: Aerospace & Defense - Development of lightweight alloys or composites with enhanced strength-to-weight ratios and improved thermal or wear resistance. - Creation of nanocomposite powders for components used in challenging environments. Automotive & Energy - Nano-enhanced powders for battery electrodes, capacitor materials, and energy storage devices. - Mechanical alloying to enable high-performance materials in motors or fuel systems. Electronics & Semiconductors - Production of nanoparticles, conductive inks, capacitors, dielectric powders, and quantum dots. - Solid-state mechanochemical synthesis of semiconductor materials like TiO₂, ZnO, CdS, and ZnS. Pharmaceuticals & Healthcare - Milling of active pharmaceutical ingredients (APIs) to improve solubility, bioavailability, or controlled release. - Nanostructured powders for drug delivery systems, scaffolds, and medical implants. Additive Manufacturing & Ceramics - Preparation of ceramic powders (e.g. alumina, zirconia) with uniform grain size and doping dispersion. - Mechanical alloying of metal powders for 3D printing and sintering processes. Key reasons why clients opt for Cal Nano include: - Experienced team: Deep know-how in setting up milling conditions, media selection, contamination control, and scaling protocols. - Custom process design: Tailoring ball milling parameters to match material types—metals, ceramics, polymers, or pharmaceuticals. - Full-service integration: Planetary ball milling combined with cryomilling, SPS sintering, analysis, and prototyping in one facility. - Quality controls and reproducibility: Tight control over parameters yields repeatable, reliable results across batches.
