Spherical Quartz Powder Properties And Applications

Posted on by adminLeave a comment
Spherical quartz powder It is made by using a carefully selected, irregular-angled, silicon micropowder for the raw material. Then, it is melted into a round shape to produce a silica powder with low stress, good fluidity, and a small specific surface.

Spherical Quartz Powder Properties

Spherical Quartz Powder has excellent properties including a smooth surface and a large surface area. It is also hard, stable, and has a high degree of chemical resistance.
The powder is fluid, and it mixes evenly with the resin. This forms a thin film. The resin content is low, while the quartz powder amount is high. This can result in a mass fraction of up to 90.5%. The more quartz powder that is added to the mold, the less thermal conductivity it has and the less thermal expansion coefficient. The performance of electronic components is improved when they are closer to monocrystalline silicon’s thermal expansion coefficient.

Second, the stress on the spherical crystal powder is 60% less than the stress on the angular quartz powder. And the plastic molding material made of spherical glass powder has the lowest concentration of stress and the greatest strength.

Finaly, the spherical-shaped powder has a smooth and non-abrasive surface with a low coefficient of friction. This can extend the life of molded parts by up to one time.

Applications for Spherical quartz powder

It has many applications. However, its main market is electronic packaging. Electronic packaging is an important industry that supports integrated circuits. The packaging requirements are increasing as integrated circuits get larger and larger.

Microelectronic packaging requires a high level of moisture resistance, low radiation, resistance to dip-soldering and reflow-soldering, as well as good plastic sealing after the integrated circuit has been packaged. Spherical Quartz Powder is a key support material in EMC. Not only does it need to have a particle size that meets the packaging range, but its purity and radioactive element content must also be low.

Quartz powder, which is spherical in shape, can be widely used for electronic packaging. It can also be used in optical fibers or high-grade cosmetics.

What Metal Melts at 90 Degrees F?

Posted on by adminLeave a comment

The melting point of a metal refers to the exact temperature at which the solid phase of a particular alloy melts and turns into its liquid phase. This point is reached when the atoms within the alloy have sufficient thermal energy to break their bonds and form a uniform liquid throughout the entire composition.

A number of different manufacturing processes require metals to be melted, such as fusion welding and casting. Knowing the melting points of different metals and alloys is essential for performing these manufacturing processes, as it allows the appropriate equipment to be selected.

Metals are known for their durability and ability to withstand high temperatures. However, certain metals are subjected to temperatures that exceed their melting points, and if a metal component begins to melt it will no longer be able to perform its intended function.

Knowing the melting points of various metals is important for anyone who works with them, including blacksmiths, jewelers and bladesmiths. These crafters often use iron in their projects, and it is helpful to know the exact melting point of this nonprecious metal.

Many people enjoy the hobby of melting metal at home. This is an easy and inexpensive way to make one-of-a-kind jewellery and other metal items. Melting metal is very simple, but it is important to maintain a safe workspace to avoid exposure to harmful chemicals and other toxic substances. The easiest metal to melt at home is aluminium, which can be obtained by simply melting down a few used soda cans in a large pot on the stove. The aluminium cans can then be poured into a mould and shaped into jewellery, cookware, ornaments or sculptures.

What are the disadvantages of using and producing silicon nitride Ceramics?
Although silicon nitride has good properties, it also has the common property of ceramics–brittleness. Silicon nitride Ceramics are polycrystalline sintered bodies made up of crystal grains with ionic or covalent bonds. The chemical bond, which is highly directional, determines low grain density, low slip systems and low energy to crack. The fracture process is characterized by the addition of fracture surface energy and the absence of any other energy dissipation mechanisms. This results in defects like low strength and inadequate toughness. It is impossible to guarantee reliability due to the fatal weakness of brittleness. The silicon nitride research has always focused on increasing its toughness, and therefore its reliability.
Why is silicon nitride so expensive?
1. The price of powder is high.
Nitrogen and high-purity silicon are required for powder preparation. Temperature, time and pressure must be carefully controlled during the nitriding procedure. The powder prepared can be ground using high energy. The whole process requires high-tech equipment. For high-purity, Nanoparticle size and high-proportion of phase purity to be achieved, equipment, technology, and even quality management requirements are high.
2. The cost of ceramics made from silicon nitride is high.
1) High sintering costs. In general, there are three types of silicon nitride silnir sintering: pressureless sintering or pressure sintering. In terms of ceramics, the quality of each method increases in a sequential manner. All three methods have advantages. The higher quality ceramics are, the more expensive they will be.
2) High processing costs. Due to its high hardness, silicon nitride must be processed using diamond abrasives. For special shape processing, special equipment will be required. Because of this, silicon nitride-based products are more costly.
