The degree of sintering directly determines the quality of polycrystalline ceramic materials (e.g., Sc 2 (WO 4 ) 3 pellets, see Figure) both functionally and structurally. It is demonstrated that the addition of boron oxide to the ceramic powder before sintering is one way to obtain highly dense bulk ceramics. Both functional characteristics (e.g., ionic conductivity) and mechanical strength are enhanced.
