dry ball milling technique

Abstract. In this paper, we present the preparation and electrical properties of nanocrystalline powders of hydroxyapatite (HAP) bioceramics, produced using the starting materials Ca(H 2 PO 4) 2, Ca(OH) 2 and a high energy dry ball milling technique. Titanium calcium phosphate (CaP-Ti) was also prepared, the raw materials Ca(H 2 PO 4) 2 and TiO 2, and examined.. The HAP was obtained of milling ...

The effect of ball milling on the crystallinity index of cellulose was also studied by Ahmad and co-workers. 26 They treated crystalline cellulose in a planetary ball mill at 600 rpm for 2 hours and studied the differences between the starting material and the final product by a range of techniques including FT-IR, X-ray diffraction, SEM and ...

A dry powder inhalable formulation of salvianolic acids

The objective of this work was to develop a new dry powder inhalable formulation intended to facilitate the access of SAL to the target place. We prepared the new SAL powder formulation containing L-arginine and 2% of lecithin using the ball milling technique. L-arginine was used to regulate the strong acidity of the SAL solution, and lecithin ...

Microparticles for sustained release of water soluble drug

Controlled release microparticles in a sub-gram-scale batch were fabricated using a ball mill, dry coating technique, to coat the water-soluble core material. This process also guaranteed the maintenance of the containment's integrity during the dry coating process. Quinine (average diameter, ca. 10 …

Ball Milling Pretreatment of Corn Stover for Enhancing the

Jul 01, 2010 Meanwhile, the results indicate that the treatment effect of wet milling is better than that of dry milling. The optimum parameters for the milling process were ball speed of 350 r/min, solid/liquid ratio of 1:10, raw material particle size with 0.5 mm, and number of balls of 20 (steel ball, Φ = 10 mm), grinding for 30 min.

High Energy Ball Mill Processing IPEN

high-energy mills. This former definition is not also adapted because the use of dry processing conflicts with examples of moist process of some materials [2]. A wider definition was proposed by Schwarz [3], for whom mechanical alloying is a high-energy ball mill technique employed to prepare powder alloys with unequal microstructure. On the
