Dear friends, we have the honor to offer you the supply of secondary concentrate containing unresolved platinum group metals. Palladium, Iridium, Rhodium. Unfortunately, the technologies of the mining company do not allow us to carry out a full cycle of rock enrichment on site, so we are looking for permanent partners to purchase concentrate as a raw material.

  Moreover, there is not enough laboratory capacity for comprehensive testing of the material, so I would like to have partners in your person to conduct analyzes and determine the crystal structure, which will affect the process of extraction and primary isolation of valuable components. We hope that our cooperation will not be limited to just trade.

1. Noble metal: Palladium is chemically inert and resistant to corrosion in most environments.

2. Catalytic properties: Excellent catalyst for many chemical reactions, especially hydrogenation and dehydrogenation.

3. Oxidation: Forms PdO oxide when heated in air, which decomposes at higher temperatures.

4. Solubility: Insoluble in most acids, but dissolves in aqua regia and concentrated nitric acid.

5. Oxidation states: Most common are +2 and +4, less frequently 0 and +1.

6. Complex formation: Forms numerous complex compounds, especially with ammonia and halogens.

7. Hydride formation: Capable of absorbing large volumes of hydrogen, forming hydrides.

8. Alloy formation: Easily forms alloys with other metals, especially those of the platinum group.

9. Reactions with halogens: Reacts with halogens to form halides.

10. Reducing properties: Can exhibit reducing properties in compounds.

尊敬的朋友們，

我們很榮幸向您提供含有未提取鉑族金屬的二次濃縮物供應(yīng)，包括鈀、銥、銠。遺憾的是，由于采礦公司的技術(shù)限制，無(wú)法在現(xiàn)場(chǎng)完成礦石的全流程富集，因此我們正在尋找長(zhǎng)期合作伙伴來(lái)購(gòu)買作為原材料的濃縮物。

此外，我們的實(shí)驗(yàn)室設(shè)備不足，無(wú)法進(jìn)行全面的材料檢測(cè)，因此希望您能夠成為我們的分析合作伙伴，共同進(jìn)行晶體結(jié)構(gòu)的分析，這將有助于提取和初步分離貴重成分的過(guò)程。我們希望我們的合作不僅限于貿(mào)易。

期待您的回復(fù)。

1. 貴金屬: 鈀在大多數(shù)環(huán)境中化學(xué)惰性,耐腐蝕。

2. 催化性能: 是許多化學(xué)反應(yīng)的優(yōu)秀催化劑,特別是氫化和脫氫反應(yīng)。

3. 氧化: 在空氣中加熱時(shí)形成PdO氧化物,在更高溫度下分解。

4. 溶解性: 不溶于大多數(shù)酸,但溶于王水和濃硝酸。

5. 氧化態(tài): 最常見(jiàn)的是+2和+4,較少見(jiàn)的是0和+1。

6. 絡(luò)合物形成: 形成多種絡(luò)合物,特別是與氨和鹵素。

7. 氫化物形成: 能吸收大量氫氣,形成氫化物。

8. 合金形成: 容易與其他金屬形成合金,特別是鉑族金屬。

9. 與鹵素反應(yīng): 與鹵素反應(yīng)形成鹵化物。

10. 還原性: 在化合物中可表現(xiàn)出還原性。

這些性質(zhì)使鈀在催化、電子和珠寶制造中具有重要價(jià)值
