Sintering Technique in Pharmaceutical Sciences: a Brief Review
نویسنده
چکیده
In the pharmaceutical science, sintering has been described as the mechanism for the strengthening of the mechanical properties of consolidated pharmaceutical powders at elevated temperatures, for solid-bond formation during tablet compression, and for thermal curing of polymer-latex film coatings. The concept of sintering was applied in the investigation of the effect of heating on the mechanical properties of pharmaceutical powders. The formation of solid bonds within a powder bed during tablet compression was also studied in terms of sintering. The changes in the hardness and disintegration time of tablets stored at elevated temperatures were described as a result of sintering. Furthermore, the sintering process has been used for the fabrication of sustained – release matrix tablets and for the stabilization of the drug permeability of film coatings derived from various pharmaceutical lattices.

Cold Sintering Process: New sintering technique for fabrication of nano-structured ceramics below 300 °C - A review
Due to the conventional understanding of sintering phenomenon in ceramic materials, considering two words of “cold” and “sintering” together may arise a doubt to a ceramic engineer since the usual sintering process has been accompanied by a heating regime at elevated temperatures. Recently, a new technique called Cold Sintering Process (CSP) has been introduced and developed as an ultra-low tem...
