求翻译：将沉淀剂和金属盐在水溶液中进行沉淀，然后再对沉淀物进行固液分离、洗涤、干燥以及加热分解等步骤处理后制得所需粉体是什么意思？

Precipitant and metal salts in aqueous solution, precipitation, and then precipitate the solid-liquid separation, washing, drying and thermal decomposition of steps to address the required powder

The sediment, and the metal salt in an aqueous solution, sediment, and then have to be solid and liquid contaminants from separation, washing, drying, as well as disintegration, and steps to deal with heating system, you need the powder

Carry on the precipitation the precipitating agent and the metal salt in the water-soluble fluid, then carries on the liquid-solid separation, the lavation again after the settling, dry as well as step processing and so on pyrolysis the system needs the powder body

Precipitation agent and metal salts in aqueous precipitation and sediment decomposition of solid-liquid separation, washing, drying and heating step is required after powder
