Nanosized a-Al 2 O 3 and CrN powders were mixed in calculated proportion and homogenized by ball milling. Cr 2 N reinforced Al 2 O 3 composites were prepared by hot pressing of nano CrN-Al 2 O 3 powders. Dense sintered bodies were obtained by hot pressing at 1400-1550 8C and 30 MPa for 60 min. X-ray

Dense Si 2 N 2 O was successfully synthesized using 2 mol% Li 2 O as an additive by a hot-pressing method at 1500 • C. Compared to other metal oxide additives, Li 2 O can significantly decrease the sintering temperature of Si 2 N 2 O, which is ascribed to the lower melting point of Li 2 O-SiO 2 and

The standard molar enthalpies of solution of cerium and lanthanum silicates (b-Ce2Si2O7 and b-La2Si2O7) in (6.20 mol•dm -3 HCl + 0.147 mol•dm -3 HF) (aq) were measured. From these values the standard molar enthalpies of formation have been deduced: DfH°m(Ce2Si2O7, cr, b, 298.15 K) = -(3807.6 2 4.5)
