What is the use of pb powder

PB Powder, also known as Pilbara Blend (operated by Rio Tinto), the grade of powder is around 61.5%, partly limonite, with good sintering performance; the grade of block is around 62.5%, belonging to limonite, with good reducibility and average thermal strength.PB Powder and block can be blended by the powder from mines such as the Tom Price Mine, the Paraboudou Mine, the Marandou Mine, the Brockman Mine, the Naimoudi Mine, and the West Anglian Mine. into.

PB powder is actually lead powder, lead is a metal chemical element, element symbol Pb, atomic number 82, atomic weight of 207.2, is the largest atomic weight of non-radioactive elements. The metal lead is a face-centered cubic crystal.

Metallic lead is a corrosion-resistant heavy non-ferrous metal materials, lead has a low melting point, high corrosion resistance, X-rays and γ-rays are not easy to penetrate, good plasticity, etc., often processed into sheets and tubes, which are widely used in the chemical industry, cables, storage batteries and radiological protection and other industrial sectors.

Lead is one of the earlier refined metals, as early as in the third millennium BC or so was discovered by mankind and application. The earliest discovery in China was the lead blocks unearthed at the Erlitou site in Yanshi, Henan Province, which existed about 3,500 to 4,000 years ago.
