Q:Are there any specific storage requirements for graphite crucibles?: Yes, graphite crucibles have specific storage requirements. They should be stored in a dry and cool environment to prevent oxidation and damage. It is essential to keep them away from moisture, direct sunlight, and extreme temperature fluctuations. Additionally, they should be stored in a clean area to avoid contamination from dust or other substances.

Q:Why is it a change of gold? Now it's black and muddy: 1., analysis of waste liquid: first, determine whether the waste liquid contains gold. In appearance, the gold waste liquid is mostly yellow. Then do a simple experiment, take the waste liquid on a clean filter paper and dry it slowly. If it is purple, it may contain gold2. reduction of gold powder: Gold liquor into the beaker, and then heated to 80-90 deg.C under stirring slowly adding ferrous chloride (or ferrous sulfate) solution, see the color of the solution changed from yellow to brown, and gradually see gold deposits at the bottom of the beaker. The precipitation, then add two drops of liquid, such as it may be considered that the blue precipitate, gold has been completely restored. Slowly pour out the liquid, spongy precipitate at the bottom of the beaker of yellow soil is the gold powder.3. purification of gold powder: in gold powder precipitation in the adsorption of some iron compound must be removed, in order to improve the purity of gold powder. With 1:2.5 hydrochloric acid into gold powder, boil, stirring for 5 minutes, then pour lotion. So 4-5 times, to the upper acid yellow for check (pickling, careful operation, reaction not too intense, so as not to spill). Then after pickling of gold powder were carefully rinsed with distilled water several times, and not so far (acidic with pH test paper).

Q:How long can a graphite crucible last for a long time?: High temperature resistance, graphite melting point is very high, in the vacuum of 3850 degrees, sublimation at low pressure, sublimation temperature of 2200 degrees, and the general material is different

Q:How to judge the thermal stability of rubber oil?: Thermal analysis method of qualitative thermal stability of 1 instrument 1.1 instrument differential thermal analyzer (DTA) and differential scanning calorimeter (DSC), temperature programmed rate at 2~30 C / min range, the precision of temperature control for soil 2 degrees, the size of power difference or temperature difference can reach 40% ~ 95% of the full scale deviation on the recorder.

Q:Can graphite crucibles be used for metal casting?: Yes, graphite crucibles can be used for metal casting. Graphite is a common material used for crucibles in metal casting due to its high melting point and excellent thermal conductivity. It is particularly suitable for casting non-ferrous metals such as gold, silver, copper, and aluminum. Graphite crucibles can withstand high temperatures without cracking or deforming, making them ideal for melting and pouring molten metal. Additionally, graphite has low chemical reactivity, which prevents it from reacting with the metal being cast. This property ensures that the purity and quality of the final cast metal are maintained. However, it is important to note that graphite crucibles may not be suitable for casting certain metals with high melting points, such as steel, as they may not withstand the extreme temperatures required for melting these metals. In such cases, other materials like clay or ceramic crucibles may be more appropriate.

Q:What is the porcelain crucible with a small hole under it?: The crucible can be divided into three categories: graphite crucible, clay crucible and metal crucible. In the graphite crucible, there are three kinds of universal graphite crucible and special graphite crucible and high-purity graphite crucible. Various types of graphite crucibles, because of their performance, application and application conditions, are different in raw materials, production methods, process technology and product models and specifications.

Q:How do you determine the appropriate crucible depth for a specific application?: To determine the appropriate crucible depth for a specific application, several factors need to be considered. These factors include the desired volume of material to be melted or held, the required thermal properties of the crucible material, the melting or holding temperature of the material, and the available space and equipment constraints. By evaluating these factors and considering the specific requirements of the application, one can determine the optimal crucible depth that ensures efficient and effective performance.

Q:Can graphite crucibles be used for melting organic materials?: Yes, graphite crucibles can be used for melting organic materials. Graphite is known for its high melting point and excellent thermal conductivity, making it a suitable material for high-temperature applications. When melting organic materials, such as polymers or organic compounds, it is important to use a crucible that can withstand the high temperatures without reacting or contaminating the material. Graphite is chemically inert and does not react with most organic substances, making it an ideal choice for melting organic materials. Additionally, graphite crucibles are typically designed to have good thermal shock resistance, allowing them to withstand rapid temperature changes during the melting process. Overall, graphite crucibles are commonly used in various industries, including chemistry and metallurgy, for melting organic materials due to their excellent heat resistance and chemical inertness.

Q:Can graphite crucibles be used for carbon fiber production?: Carbon fiber production can utilize graphite crucibles, which are often employed in high-temperature situations due to their exceptional thermal conductivity, high melting point, and chemical resistance. To create carbon fiber, graphite crucibles can be utilized to heat and liquefy the precursor materials like polyacrylonitrile (PAN) or pitch. These materials then undergo a series of steps to generate carbon fiber. Graphite, known for its high-temperature stability and lack of reactivity, serves as an ideal substance for maintaining the necessary conditions during the carbonization process. Furthermore, the smooth surface of graphite crucibles plays a significant role in achieving uniform heat distribution, an essential factor in ensuring the quality and consistency of carbon fiber production. As a result, graphite crucibles prove to be a suitable choice for the production of carbon fiber.

Q:Is the silicon carbide crucible good for use? What's the difference between an ordinary graphite crucible and a graphite crucible?: The silicon carbide crucible is a bowl shaped container with a ceramic bottom. When solids have to be heated by fire, the crucible must be used. Because it is more able to withstand high temperatures than glass. When used, the crucible does not usually fill the melt too much to prevent the heat from jumping out and allowing the air to pass in and out freely for possible oxidation. Because the bottom of the pot is very small, it usually needs to be placed on the clay triangle to heat it directly.
