Hydroxyapatite Porous Ceramics Fabrication

Check if the same lab product or an alternative is used in the 5 most similar protocols
The HAPPs were prepared by using paraffin spheres with diameters of about 3 mm and about 0.8 mm as the pore-forming agents, respectively, according to the preparation method of our earlier publication [30 (link)]. Briefly, HA powders were dispersed in a chitin-lithium chloride solution in dimethylformamide (all from Chengdu Kelong Chemical Co., Ltd., China) to form a suspension. Subsequently, the melting paraffin was dropped into a stirred polyvinyl alcohol (PVA, Chengdu Kelong Chemical Co., Ltd., China) to form the paraffin spheres. These spheres were then accumulated in a cylindrical mold and immersed in xylene (Chengdu Kelong Chemical Co., Ltd., China) and given pressure for a while to control the inter-sphere connectivity. The HA suspension was infused and gelled with water in air. Paraffin was wiped off by immersing in n-hexane (Chengdu Kelong Chemical Co., Ltd., China). The initial scaffolds were sintered into ceramic objects (Figure 2). The two macro-pore sizes of HAPPs were labeled L-HAPPs and S-HAPPs, respectively.
All the scaffolds were sealed in vacuum packages and sterilized with ethylene oxide for subsequent implantation.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
