An amorphous salt was precipitated by reacting barium bromide with a solution of peroxo-polytungstic acid. Heating it in a hydrogen stream at temperature near 550Β°C yielded a hexagonal form of barium tungsten bronze, Ba,WO,, in a pure phase with n being in the range 0.19-0.24. At temperature higher

## Abstract Calcium phosphate bulk materials were fabricated via chemical bonding technique with the use of Ξ±βtricalcium (TCP) and amorphous calcium phosphates (ACP) as binders at temperatures below 90βΒ°C. The bonding technique included preparation of pastes of the binders with water, pressing the
