Waste glass and reclaimed brick are types of construction demolition waste (C&DW) that could potentially be used as secondary raw materials in the production ceramics. Ceramics based on clay, demolished (5-15 wt.%) (5-20 were produced by pressing (P = 68 MPa) subsequently sintered at 900, 950, 1000, 1050 oC for one hour. The physical mechanical properties ceramics obtained evaluated. additi...

BACKGROUND An increase in surface roughness of ceramics may decrease strength and affect the clinical success of ceramic restorations. However, little is known about the effect of acidic agents on ceramic restorations. The aim of this study was to evaluate the surface roughness of dental ceramics after being immersed in acidic agents. METHODS Eighty-three ceramic disk specimens (12.0 mm in di...

Structural characterization of historical materials, especially clay-based compositions, as well as technical and archaeological aspects, has a significant role in the diagnosis of the deterioration process. One of the most important parameters in the structure of clay-base ceramics (such as pottery, brick, and tile ware) is porosity that includes all open and closed pores in the matrix of poro...

Europium doped transparent lead fluorophosphate glass ceramics successfully were prepared with heat treatment of precourse glasses at temperature above glass transition (Tg). X-ray diffraction (XRD) experiment evidenced the formation of PbF2 nanocrystals in glassy matrix. The emission spectra investigation indicate that considerable amount of Eu3+ ions were trapped in crystalline phase, and the...
