The quantity of sewage sludge generated daily by wastewater treatment plants represents a major environmental problem and financial burden for plant operators. Valorization strategies focusing on reusing as raw material are currently developed. Vitrification can help us reduce the volume waste binds components in structure chemically stable glasses glass-ceramics. In this study, vitrification i...

Nano-coated particles and whiskers were used as reinforcing additives for ceramic tool materials to take advantage of synergistic toughening enhancement mechanisms. An Al2O3/TiC/CaF2@SiO2/SiCw material was fabricated by hot-pressing. Self-lubricating toughened nano CaF2@SiO2 coated SiC studied. When the addition content 10 vol% 20 vol%, with best comprehensive properties obtained. The results s...

The 70SiO2-15TiO2-15ZrO2 membrane was prepared by a sol-gel procedure. The corrosion behavior of microporous toplayers along with the membrane characterization in terms of pore size, surface area, pore volume and weight loss is described. The final ceramic membrane with a thickness of 400 nm and uniform surface was obtained. This membrane confirmed the fine microporous characteristic with mean ...

Molecular dynamics simulations allow to investigate the microscopic evolution of a structure, and can also point way tool material design. In this paper, effect adding CaF2 CaF2@SiO2 on Si3N4/TiC system is studied using molecular simulations. The results show that with addition model has higher hardness than CaF2. order obtain optimum parameters for self-lubricating ceramic tools, different amo...

There are few works in the literature regarding study and development of new bioceramic compounds for ophthalmologic applications, especially considering use advanced laboratory technologies such as sol-gel process, which presents possibility controlling various parameters namely temperature, stoichiometry alkalinity. In this regard, present work synthesized alumina-based combination with silic...

Cobalt–chromium (CoCr) alloy is widely used for medical implants such as dental or joint replacements because of its strength and high corrosion resistance. By throwing a spherical media against material surface, fine-particle shot peening can modify surface properties and, result, has been low-cost simple method to increase metal’s wear However, no recent literature reported the effect particl...
