Abstract: This invention provides sputtering target materials having high reflectance and excellent heat resistance, which are formed of Ag base alloys formed by adding a specific, minor amount of P to Ag and alloying them.

Abstract: A spark plug for use in an internal combustion engine has a center electrode, an earth electrode, and an electrode chip formed on at least one of the center electrode and the earth electrode. A spark discharge gap is formed between the center electrode and the earth electrode. The electrode chip has a base section, a chromium rich layer formed on at least a part of the base section, and a diffusion layer formed between the base section and the chromium rich layer. The base section contains chromium within a range of 5 to 45 mass %, an element X within a range of 0.5 to 25 mass %, and a remainder composed of tungsten and unavoidable impurity. The chromium rich layer is larger in content of chromium than the base section. The element X contained in the base section is comprised of at least one of molybdenum, silicon, aluminum and lead.

Abstract: A spark plug has a center electrode and an earth electrode. The center electrode is faced to the earth electrode so that a spark discharging gap is formed between the center electrode and the earth electrode. An electrode chip is formed on at least one of the center electrode and the earth electrode. The electrode chip has a composition comprised of 40 to 60 mol % of aluminum and iridium as a remainder thereof. In the composition of the electrode chip, it is possible to replace part of the iridium with 1 to 20 mol % of at least one metal selected from nickel, iron, cobalt, platinum and rhodium.

Abstract: Disclosed are magnetic thin films, sputtering targets and vapor deposition materials, each of which is composed of 40-60 at % of Pt, 40-60 at % of Fe, 0.05-1.0 at % of P and furthermore depending on the occasions, 0.4-19.5 at % of Cu and/or Ni.

Abstract: Provided is a conductive material to be used for a resistor and a sensor, which is enhanced its mechanical strength while maintaining a stable resistance ratio. In the conductive material used for the resistor and the sensor, 400 to 10,000 ppm of Sr is contained in Pt, and the balance is an inevitable impurity. An intermetallic compound phase formed of Pt and Sr is precipitated and dispersed in Pt.
