  • Effect of ZrO2 Additives on the Nanomechanical Properties

    in a glove box under an argon gas atmosphere. The milling process was carried out for 20 h at room temperature using a high-energy mixer ball mill. The milling procedure was repeated 25 times in order to obtain approximately 350 g of ultrafine nanocrystalline WC powder for the preparation of WC-based nanocomposite materials. The as-ball-milled

  • BALL-MILLING OF TiO2 AND ZrO2hu-berlin

    2 and their mixtures was performed in air using Fritsch planetary ball mill "Pulverisette 6" with vial and balls made of zirconia (94 ZrO 2). The speed of mill rotation was 500 rpm. Two different powder-to-ball weight ratios (R) 1 50 and 1 10 were used. The milling time varied from 1 min to 10 hours.
