Technology Offer Ref.ID: APC-5098TO Silver-tin Oxide Electrical Contact MaterialsCountryIndia DescriptionIndian non-profit organisation engaged in research, technology development, and consultancy offers the technology of silver-tin oxide electrical contact materials. Silver-tin oxide materials are used in low voltage contactors, low voltage circuit breakers, relays with high make current peaks, capacitor switchgears for making and breaking high currents. The material is used in the form of buttons. The material is a two layered structure. The top layer consists of silver-tin oxide, whereas the bottom layer, required for brazing to the carrier is silver-rich layer. The thickness of the silver-rich layer is 1/10th that of the total thickness. The process involves resistance/induction melting of silver-tin alloy alongwith a few ingredients. The melted alloy is rolled to the desired thickness. The alloy is given intermediate annealing to facilitate rolling. A silver layer is diffusion bonded on one side of the sheet. Pieces of desired shape and size are punched out. These pieces are heated in the oxygen atmosphere at a predefined temperature for different length of time depending upon the thickness of the piece. the pieces are taken out the furnace and ready to be brazed to the carrier. In a alternative process, silver and tin oxide powders are mixed in a ball mill. The mixed powder is pressed in a die. In the second stage, silver powder is added in the same die and pressed. The pressed green compact is sintered at a given temperature for definite time. The repressed pieces are annealed to obtain the final component. Areas of ApplicationLow voltage contactors, motor switches and moulded case circuit breakers with rated current of about 10 ampere to largest types of devices. Low voltage circuit breakers with rated current upto 200 amperes

Silver-tin oxide also has better anti-erosion and anti-welding properties as compared to Ag-CdO All the materials are non-toxic and do not cause any environmental hazard Production Capacity1 million tips of 7.6 mm dia and 1.4 mm thickness Inputs RequiredRaw materials: Silver, tin, indium, nickel, oxygen gas, nitrogen gas Land: 20 x 20 sq.m. Built-up area: 250 sq.m. Water: dry process, may be needed for cooling the furnaces Manpower: 4 total, including 1 skilled, 1 unskilled and 1 technician Power: 20,000 units...
