Products

This series features trimethylaluminum (TMA), hexaamminecobalt(III) chloride, colloidal antimony pentoxide, antimony glycolate and high-purity alumina (99.999 %). Target high-end-manufacturing fields include semiconductor thin-film deposition (ALD / CVD), polyester catalysis, electronic ceramics and optical coatings. Unlike ordinary chemicals, value lies not only in chemical purity but also molecular-structure integrity, dispersion stability, particle-size uniformity and process compatibility. Our core technical competence originates from long-term strategic cooperation with materials-science departments of leading universities in Hong Kong and Guangzhou. Multiple technical breakthroughs and industrial implementations have been achieved for core-shell composite powders and ultrafine rare-earth oxides. For quality assurance: laser particle-size analysers paired with standardised dispersion protocols control particle dimensions; cross-validation via ICP-MS, GDMS and other analytical techniques delivers precise impurity control. For precursors with special packaging-and-transport requirements such as TMA, we provide custom-container solutions (bubbler cylinders, stainless-steel vessels etc.) together with complete technical documentation (TDS, ICP-MS reports, SDS). This shortens customer material-qualification cycles and mitigates supply-chain-adoption risks.
  • Cesium Tungsten Bronzes(Cs0.32WO3) Assay Min.99.5% Cas 189619-69-0

    Cesium Tungsten Bronzes(Cs0.32WO3) Assay Min.99.5% Cas 189619-69-0

    Cesium Tungsten Bronzes(Cs0.32WO3) is a near-infrared absorbing nano material with uniform particles and good dispersion. Cs0.32WO3 has excellent near-infrared shielding performance and high visible light transmittance. It has strong absorption in the near-infrared region (wavelength 800-1200nm) and high transmittance in the visible light region (wavelength 380-780nm). We have the successful synthesis of highly crystalline and high purity Cs0.32WO3 nanoparticles through a spray pyrolysis route. Using sodium tungstate and cesium carbonate as raw materials, cesium tungsten bronze (CsxWO3) powders were synthesized by low temperature hydrothermal reaction with citric acid as the reducing agent.

  • Antimony Pentoxide colloidal Sb2O5 widely used as flame retardant additive

    Antimony Pentoxide colloidal Sb2O5 widely used as flame retardant additive

    Colloidal Antimony Pentoxide is made through a simple method based on reflux oxidization system. UrbanMines has detailedly investigated about the effects of experimental parameters on the colloid stability and size distribution of the final products are carried out. We specialize in offering colloidal antimony pentoxide in a wide range of grades developed for specific applications. The particle size ranges from 0.01-0.03nm up to 5nm.

  • Ethylene Glycol Antimony

    Ethylene Glycol Antimony

    Ethylene glycol antimony is a new, high‑efficiency catalyst for polyester polycondensation. Compared with traditional catalysts (antimony trioxide, antimony acetate), it offers distinct core advantages:
    Superior solubility and dispersibility
    It exhibits significantly higher solubility in ethylene glycol and disperses uniformly. This effectively prevents catalyst agglomeration, ensures a stable reaction system, and minimizes dead zones.
    Higher catalytic activity
    With a high antimony content and strong catalytic activity, it notably accelerates polyester polycondensation, shortens reaction cycles, increases plant capacity and productivity, and reduces production costs.
    Enhanced product quality
    High purity prevents introduction of additional impurities into the reaction system. It improves the intrinsic quality of polyester chips, enhances spinnability, streamlines downstream spinning processes, and delivers fibers with superior strength and toughness.
    Developed and customized by UrbanMines, ethylene glycol antimony features stable physicochemical properties, high catalytic efficiency, and significant quality improvement. It has become the preferred catalyst for polyester process upgrades and is suitable for all polyester polycondensation applications.

  • Trimethylaluminum(TMAI)

    Trimethylaluminum(TMAI)

    Trimethylaluminum (TMAI) is a critical raw material for the production of other metal-organic sources utilized in atomic layer deposition (ALD) and chemical vapor deposition (CVD) processes.

    Trimethylaluminum represents one of the simplest organoaluminum compounds. Although its name suggests a monomeric structure, it actually has the formula Al2(CH3)6 (abbreviated as Al2Me6 or TMAI), existing as a dimer. This colorless liquid is pyrophoric and plays an industrially significant role, closely related to triethylaluminum.

    UrbanMines ranks among the leading suppliers of Trimethylaluminum (TMAI) in China. Leveraging our advanced production techniques, we offer TMAI with varying levels of purity, tailored specifically for applications in the semiconductor, solar cell, and LED industries.

  • Aluminum oxide alpha-phase 99.999% (metals basis)

    Aluminum oxide alpha-phase 99.999% (metals basis)

    Aluminum Oxide (Al2O3) is a white or nearly colourless crystalline substance, and a chemical compound of aluminum and oxygen. It is made from bauxite and commonly called alumina and may also be called aloxide, aloxite, or alundum depending on particular forms or applications. Al2O3 is significant in its use to produce aluminum metal, as an abrasive owing to its hardness, and as a refractory material owing to its high melting point.
