  • Hydrothermal crystallization kinetics of m-ZrO2 and t-ZrO2

    The isothermal nucleation and crystallization kinetics of hydrothermally prepared monoclinic and tetragonal ZrO 2 have been determined at various pH conditions. It is shown that monoclinic ZrO 2 precipitates at low pH whereas at high pH tetragonal ZrO 2 crystallizes from an amorphous zirconium (hydrous) oxide Zr(OH) x O y precursor.At intermediate pH conditions mixtures of the polymorphs are

  • Synthesis of Nanomaterials by High Energy Ball Milling

    In particular mechanical attributed contamination by the milling tools (Fe or WC) as well as ambient gas (trace impurities such as O 2 N 2 in rare gases) can be problems for high-energy ball milling. However using optimized milling speed and milling time may effectively reduce the contamination.

  • Formation and Properties of the Ta-Y2O3 Ta-ZrO2 and Ta

    The nanocrystalline tantalum-ceramic composites were made using mechanical alloying followed by pulse plasma sintering (PPS). The tantalum acts as a matrix to which the ceramic reinforced phase in the concentration of 5 10 20 and 40 wt. was introduced. Oxides (Y 2 O 3 and ZrO 2 ) and carbides (TaC) were used as the ceramic phase.

    Dec 23 2005 · The dilute acid (0.05 M H2SO4) hydrolysis at 175 °C of samples comprised of varying fractions of crystalline (α-form) and amorphous cellulose was studied. The amorphous content based on XRD and CP/MAS NMR and the product (glucose) yield based on HPLC increased by as much as a factor of 3 upon ball milling. These results are interpreted in terms of a model involving mechanical

    A solid state reaction in an equimolar mixture of TiO 2 and ZrO 2 was achieved by high‐energy ball‐milling. The ball‐milling first induced the transformation of anatase TiO 2 to high‐pressure phase TiO 2 (II). Nanosized ZrTiO 4 phase was formed from TiO 2 (II)/ZrO 2 solid solution by prolonging milling. The finishing of the solid state reaction towards ZrTiO 4 ceramic is investigated
