متن کاملInfluence of the formulation of an alumina powder on compaction
The compression of ceramic powders requires the addition of organic materials to insure tablet cohesion. For the compaction of formulated ceramic powders it is necessary to supply them energy. As a function of the formulation of ceramic powders, one can measure the specific energy acquired during the tablet compression. Recently, a technique used in powder metallurgy, High Velocity Compaction (...
متن کاملThe Effect of Silica Coating on the Drug Release Profile and Biocompatibility of Nano-MOF-5
The purpose of this study was the surface modification of nano MOF-5 (NMOF-5) or IRMOF-1 (Zn4O(C8H4O4)3) in order to prevent its rapid degradation in the phosphate-buffered saline (PBS), along with the simultaneous increase in its biocompatibility. The NMOF-5 sample was synthesized under the ultrasound irradiation and then it was loaded wit...
متن کاملInfluence of nano alumina coating on the flexural bond strength between zirconia and resin cement
PURPOSE The purpose of this in vitro study is to examine the effects of a nano-structured alumina coating on the adhesion between resin cements and zirconia ceramics using a four-point bending test. MATERIALS AND METHODS 100 pairs of zirconium bar specimens were prepared with dimensions of 25 mm × 2 mm × 5 mm and cementation surfaces of 5 mm × 2 mm. The samples were divided into 5 groups of 2...
متن کاملEffect of pH on the combustion synthesis of nano-crystalline alumina powder
Synthesis of nano-crystalline alumina powder by a chemical pyrophoric reaction using citric acid and ammonia was investigated by varying the pH of the precursor solution, which played an important role in controlling the morphology of the synthesised powder. The flaky morphology obtained at pH = 2 could be modified to fine desegregated particulate form by varying the pH of the solution to 10. T...
