1. Rhodium-ruthenium alloy: a binary alloy containing ruthenium based on rhodium. The maximum solubility of ruthenium in rhodium is >20%, and the as-cast Vickers hardness of RhRu10 alloy is 1344. The rhodium-ruthenium alloy is smelted with argon protection in a high-frequency induction heating furnace.

2. Ruthenium series resistance paste: the most widely used resistance paste composed of electrically conductive materials (ruthenium dioxide, bismuth ruthenate, lead ruthenate, etc.), glass binder, organic carrier, etc., with a wide range of resistance values. , Low temperature coefficient of resistance, good resistance reproducibility, good environmental stability, etc., used to make high-performance resistors and high-reliability precision resistor networks.
3. Ultrafine hydrated ruthenium dioxide powder: black or blue-black ultrafine powder for the production of thick film resistor paste or catalyst, wherein the mass fraction of ruthenium is 60% to 71%. The average particle size of the powder is less than 1.0um, the bulk density is 0.5~0.9g/cm, and the tap density is 1.0~1.4g/cm-3.
