“…The samples were weighed in the water-immersed state by using the above mentioned balance equipped with an 'AD-1653' density determination kit, after which their surface was dried with a piece of water-saturated cloth to remove water droplets from their surface before the saturated weight of the samples was determined. the open porosity, closed porosity as well as the pore volumes were then calculated using formulae (2)(3)(4)(5)(6).…”

The current investigation presents porous ceramic materials prepared of cenospheres prepared by spark plasma sintering. The impact of sintering temperature, mould diameter (20 and 30 mm diameter) and cenosphere size on the properties of the sintered material was investigated. Shrinkage of the samples during sintering started at 900 °C. Sample shrinkage during sintering increases with increasing temperature and decreases with increasing mould size; increasing sample sintering temperature increases the apparent density of all sample series CS 63-150 µm in 20 mm mould from 0.97 to 2.3 g·cm-3 at 1050 - 1300 °C, in 30 mm mould 0.81 - 1.87 g·cm-3 at 1050 - 1200 °C, in 50 mm mould 0.54 - 0.75 g·cm-3 at 1050 - 1150 °C, while CS 150-250 µm in 20 mm mould 0.93 - 1.96 g·cm-3 at 1050 - 1200 °C. Total porosity decreases from 61.5% to 3.9% with increasing sintering temperature from 1050 to 1250 °C, while open porosity reduces at lower temperatures, with closed porosity being highest in samples sintered at 1150 °C. When the sintering temperature increases from 1050 to 1300 °C, the compressive strength of the CS 63-150 samples produced in a 20 mm mould increases from 11 MPa to 312 MPa. These results correlate with the Rice model, which describes an exponential dependence of compressive strength on material porosity and fully dense material compressive strength.

“…When developing a composite material, it becomes feasible to combine the distinctive properties of various materials into one [1]. To guarantee a high level of strength in the composite, it is essential to incorporate a material inherently to have high strength [2,3]. 2 One of the promising of material structures is a syntactic foam (SF).…”

The current investigation presents porous ceramic materials prepared with cenospheres (CS) by using spark plasma sintering. The impact of sintering temperature, mould diameter (20, 30 and 50 mm) and cenosphere size on the properties of the sintered material was investigated. Shrinkage of the samples during sintering started at 900 °C. Total sample shrinkage during sintering increases with increasing temperature and decreases with increasing mould size; increasing sample sintering temperature increases the apparent density of all sample series CS 63–150 µm in a 20 mm mould from 0.97 to 2.3 g·cm−3 at 1050–1300 °C; in a 30 mm mould, 0.81–1.87 g·cm−3 at 1050–1200 °C; in 50 mm mould, 0.54–0.75 g·cm−3 at 1050–1150 °C; while CS 150–250 µm in a 20 mm mould is 0.93–1.96 g·cm−3 at 1050–1200 °C.
