Hydrothermal synthesis and sintering of ultrafine CeO2 powders

What is CeO2?Nanocrystalline cerium(IV) oxide (CeO2) powders were prepared by heating solutions of cerium(IV) salts in the presence of urea under hydrothermal conditions at 120° to 180°C. The effects of urea concentration and hydrothermal treatment temperature on the morphology and crystallite size of the synthesized particles were investigated. The synthesized particles were angular, ultrafine CeO2 with a cubic fluorite structure. Their crystallite size decreased from 20 to 10 nm with increasin

Materials and Processing of Hollow glass powder

The matrix material PA2200, with an average particle size of 60μm and a white appearance, was obtained from EOS GmbH in Germany. Moreover, the mixing ratio of new and old powder is 1:1. Filler additives, Hollow glass powder was surface treated with silane coupling agent supplied by The Minnesota Mining and Manufacturing(3M) Company in the USA. As an inorganic material, Hollow glass powders have no polarity and poor compatibility with PA2200. Thus, the mechanical properties of sintered parts of P

Processing and properties of Hollow glass powder particulate

Selective laser sintering (SLS) to prepare composites by adding filler into the polymer effectively saves costs and reinforces the sintered parts. This article investigated the fabrication of PA2200 composites filled with different volume fractions of Hollow glass powder (HGM) by SLS. HGM was prepared by silane coupling agent surface treatment. The particle size distribution, microstructure, and thermal and mechanical properties of PA2200/HGM composites were studied by scanning electron microsco

What are Silicon Nitride Properties?

Silicon nitride is taken into consideration an extremely important design ceramic. At heats, silicon nitride displays excellent mechanical properties, consisting of reduced thickness, high flexing toughness, high elastic modulus, crack toughness, high wear, and also resistance to strong bit erosion. The product also shows exceptional thermal homes, reduces expansion and contraction due to temperature level, as well as can stand up to thermal shock (fast, significant temperature adjustments). Las

Can I make silica at home

Mix 5 ml sodium silicate solution and 5 ml water. Mix 3.5 grams of sodium bisulfate in a separate container into 10 mL of water in a glass stirrer. Keep stirring until the sodium bisulfate dissolves. Mix the two solutions. Silicon and silica are two different chemical species. The key difference between Silicon and silica is that Silicon is a chemical element, whereas silica is a chemical compound. Silica has a higher melting point than Silicon.Further, Silicon is a semiconductor, but silica doe
