Aug 01, 2017 Aug 01, 2017 A high speed vibrating ball-milling machine (QM-3B, Nanjing NanDa Instrument Plant, Nanjing, China) was employed to exfoliate graphite into GNPs. All the electrochemical measurements were performed on a CHI 660A analyzer (CH Instruments, Shanghai, China). 2.3. Ball-milling synthesis of GNP inks

Nanjing NanDa Instrument Plant) at room temperature. For single ball-milling, microcrystalline cellulose was charged in a 100-mL ZrO 2 container, and the ball-milling was carried out at a speed of 500 rpm with ZrO 2 balls (15 balls, Φ=7 mm) for 0-4 h. For mixed ball-milling, microcrystalline cellulose and the solid acid catalyst were charged in

Jun 26, 2020 The mechanical milling was executed by a QM-3SP4 type planetary ball milling machine (Nanjing NanDa Instrument Plant, Nanjing, China). Through the preparation experiment, the optimum milling parameters were determined, which were given as follows: the mass ratio of ball to powder was 60:1 and the shaft rotation was 300 rpm. Then, the AZ31/TiB

Ball-milling of cellulose was conducted using a planetary ball mill (QM-3SP04, Nanjing NanDa Instrument Plant) at room temperature. For single ball-milling, microcrystalline cellulose was charged in a 100-mL ZrO 2 container, and the ball-milling was carried out at a speed of 500 rpm with ZrO 2 balls (15 balls, Φ=7 mm) for 0-4 h

planetary ball mill (Nanjing NanDa Instrument Plant, China) under argon atmosphere (dry milling). The milling tools were made from tungsten carbide (WC) with a cobalt (Co) binder. The rotational speed was 250 rpm. Five different powders were singly prepared and the ball milling times were 0.5, 10, 40, 80 and 120 h, respectively. The mass ratio

Milling was performed in a QM-QX planetary ball mill (Nanjing NanDa Instrument Plant) at a rotation speed of 500 rpm for 1 h. The milled mixture was calcined in air at 250 oC for 2 h firstly, and then calcined in air at 450 oC for 2 h, giving the expected CeO2/TiO2 catalyst. The catalyst prepared by dry ball milling using cerium (III) nitrate

The planetary ball mill is a necessary device used for high-tech materials ' mixing, fine grinding, sample preparation, new product development and small batch production. Featuring small volume, high efficiency and low noise, it is an ideal equipment for R&D institution, colleges and universities, enterprises and laboratories to obtain samples

Mechanical alloying (MA) was carried out in a planetary ball mill (QM-3SP4, Nanjing NanDa Instrument Plant, China) for 2h–50h at room temperature under protection of argon atmosphere

Jan 31, 2017 Jan 31, 2017 The LiBH4/CaH2 composite according to the stoichiometric ratio are synthesized by high-energy ball milling method. ... atmosphere by using a QM-2B high energy mill (Nanjing NanDa Instrument Plant

Product Description. Planetary Ball Mill. Model: QM-3SP4. 1. Purpose. QM series planetary ball mills could grind or mix solid particles of different granularities and materials, suspension and paste with dry and wet methods. If a vacuum ball milling tank is used, it will be possible to grind and mix samples in vacuum or inert gases
