Joining of silicon carbide by a heat-resistant phosphate adhesive

A SiC whisker reinforced high-temperature resistant phosphate adhesive for bonding carbon/carbon composites

“…5 that most of Si was oxidized into SiO 2 and there were borosilicate glass and mullite generated in both adhesives as temperature increased from 900°C to 1300°C. The oxidation of Si also produced volume expansion [37], causing the adhesive in Fig. 6C was more compact than that in Fig.…”

Influence of expansion admixtures on the properties of water‐glass‐based refractory pastes

“…Then, they were bound by the pastes and the shear strength of the joint was used to evaluate the bonding strength of the pastes. The adhesion method, shear strength test fixture and conditions were explained in Ref . The relative volume was determined by the following equation: relative volume=( V 1 ‐ V 0 )/ V 0 ×100%, where V 1 and V 0 are the volumes of calcined pastes cubes and the mold cavity (8 cm 3 ), respectively.…”

“…The adhesion method, shear strength test fixture and conditions were explained in Ref. 25 The relative volume was determined by the following equation: relative volume=(V 1 -V 0 )/V 0 9100%, where V 1 and V 0 are the volumes of calcined pastes cubes and the mold cavity (8 cm 3 ), respectively. The density was mass divided by volume, and the open porosity was determined by a kerosene-immersion technique using the Archimedes method.…”

Eco-benign PVA/aluminum phosphate as an alternative to formaldehyde-based adhesives in wood-based panels

“…5 They exhibited outstanding properties such as simple preparation technology, low-cost production, slight curing shrinkage, short production cycle, high-temperature resistance, abrasion resistance and excellent bonding strength. [6][7][8] Phosphoric acid undergoes three ionization steps associated with the three phosphate ions; namely, H 2 PO 4 À, HPO 4 2À and PO 4 3À , and they are known as ligands of monodentate, chelating or bridging forms. 9 The strengthening of the binder is due to the chemical bonding of phosphate phases and a change in the stress state.…”

“… 17 Si and B 4 C as the inorganic fillers were added to the formation of borosilicate glass. 8 CrO 3 was added into aluminum phosphate binder, which could achieve excellent rehydration resistance with low thermal conductivity. 9,18 AlN, NH 4 F, MgO and ZrO 2 were added to AP, lowered the hardening-temperature, and improved rehydration resistance.…”
