Embodiment 1
[0032] A dental palladium-silver alloy material, the alloy contains the following main components by weight percentage: palladium (Pd) 57.6%, silver (Ag) 28.1%, and the balance is other alloy elements, specifically indium, gold, platinum, At least one of gallium, zinc, tin, copper, antimony, carbon, germanium, zirconium, silicon, selenium, iron, magnesium, aluminum, cobalt, titanium, iridium, rhodium and other elements. In this embodiment, 11.4% indium and 2.9% gallium are used as a demonstration.
[0033] Batching is carried out according to the above weight composition ratio; the prepared raw materials are put into the melting furnace for smelting; the smelted metal molten liquid is poured into the mold to make the blank; respectively under the protection of nitrogen and nitrogen-hydrogen mixed gas Perform annealing treatment on the preform; roll the annealed preform into a cube or cuboid sample of about 1 g.
[0034] The obtained sample has a liquidus temperature of 1240°C, ...
