What is the method of making tin powder?

The centrifugal atomisation method of making conventional tin powder is widely used in industry. The main mechanism is to fill a large airtight container with an inert gas. A high-speed rotating disc is fixed at the top of a high-speed motor, and the disc speed is adjustable; the molten liquid alloy with qualified composition check is flowed (dripped) to the rotating disc through a pipe, and the centrifugal force generated by the rotation of the disc throws out the liquid solder, which, driven by the surface tension of the metal droplets, balloons into small droplets, which cool down under the inert gas environment to form spherical metal particles, which are gathered at the bottom of the closed container, and tin powder is finally obtained.

The Difference in Production Methods Between Green Silicon Carbide and Black Silicon Carbide

Silicon carbide (SiC) is an important inorganic non-metallic material with high hardness, wear resistance, and high-temperature resistance, making it widely used in many fields. Silicon carbide can be divided into green silicon carbide and black silicon carbide based on color. The production method of green silicon carbide is the same as that of black SiC, but the requirements for raw materials are different. The crystalline form of green silicon carbide obtained through smelting has high purity and hardness.The production method of green silicon carbideThe production method of green silicon carbide mainly includes raw material preparation, crushing, batching, forming, sintering, etc.Raw material preparation: The main raw materials for green silicon carbide are petroleum coke and quartz sand. Petroleum coke requires high fixed carbon content, low sulfur content, low ash content, and low volatile content, while quartz sand requires high SiO2 and low impurity content.Crushing and batching: Crush and mix petroleum coke and quartz sand in proportion, and then feed the mixed raw materials into the molding machine through batching equipment.Forming: In the molding machine, raw materials are pressed into green billets with a certain shape and size.Sintering: Put the green body into a high-temperature furnace so that the carbon in the green body reacts with SiO2 in quartz sand to generate SiC, thereby obtaining green silicon carbide products.The production method of black silicon carbideThe production method of black silicon carbide also includes steps such as raw material preparation, crushing, batching, forming, sintering, etc. However, its raw materials and process parameters are different compared to green silicon carbide.Raw material preparation: the main raw materials of black silicon carbide are coal tar oil coke and quartz sand, of which coal tar oil coke requires high fixed carbon content, low sulfur content, low ash content, and moderate volatile content, while quartz sand requires the same requirements as green silicon carbide.Crushing and batching: Coal tar, oil coke, and quartz sand are crushed and mixed in a certain proportion, and then the mixed raw materials are fed into the molding machine through batching equipment.Forming: In the molding machine, raw materials are pressed into green billets with a certain shape and size.Sintering: Put the green body into a high-temperature furnace so that the carbon in the green body reacts with SiO2 in quartz sand to generate SiC, thereby obtaining black silicon carbide products.It should be noted that during the sintering process, black silicon carbide's sintering temperature is higher than green silicon carbide's, and longer insulation time is required to achieve higher density and performance.About RBOSCHCORBOSCHCO is a trusted global chemical material supplier & manufacturer with over 12 years experience in providing super high-quality chemicals and Nanomaterials.
