Silicon Wafers

Silicon is the 2nd most abundant element in the universe by mass, making up 25.7% of the crust. It rarely occurs as the pure element in nature more widely appeared as a compound most common form is SiO2, or silica dioxide. It has many industrial applications, one of the most used application is in electronics in the form of pure silicon. Pure silicon is the principal component of most semiconductor devices, most importantly integrated circuits or computer chips. It is prepared as wafers with high purity and crystallinity and cut into ships to be used in most electronic devices. Silicon wafers are also widely used in solar cells for their good photovoltaic properties.
There are different types of silicon wafers made for different applications. They differ according to the preparation methods and the material used for the preparation. For example,monocrystalline Czochralski silicon wafers (Cz-Si Wafers) are widely used in electronic ships because of its production in large cylindrical ingots. Other type of wafer is Float-zone silicon wafers (Fz-Si Wafers) which have high purity are used in detector applications and to fabricate optical components.

Usage of Silver Conductive Adhesive Paste in Corrosion Protection

In electronics, solders are main material to connect electrical components to substrates which are generally printed circuit boards. Although they are cheap, they are not effective if long term performance is considered since solders have low resistivity to corrosion relatively. Since corrosion reduce reliability, the cost of advanced technological systems such as RADAR, SONAR, LIDAR and more increase. In addition, small signals can be lost, and in huge data transfer, some of the data can be lost also especially which may lead catastrophic failures in critical systems. For instance, surface to air missiles can be launched to target which is not exist if the data coming from detection systems is noisy. Therefore, corrosion protection is necessary, and  silver conductive adhesive paste  is an essential candidate to replace PbSn solders due to its resistivity to corrosion. Silver conductive adhesive paste provide not only noisy reduction but also electromagnetic interference whi...

Nanocellulose: Descriptions, Usage and Applications

Nanocellulose  is denoted by nano-structured cellulose which consist of C6H10O5. Since cellulose is abundant polymer in nature, large quantity of nanocellulose can be manufactured from the cost-effective aspect. Non-toxic and lightweight properties make it easy to carry, so it can be used in applications which requires mobility. High tensile, stiffness and electrical conductivity expand its usage through electrical and mechanical applications. Unique properties depending on the type of nanocellulose are also exist. There are three types which are cellulose nanocrystal (CNC), cellulose nanofibers (CNF), and bacterial nanocellulose (BNC). First type of nanocellulose is  cellulose nanocrystal , development in applications show that CNCs have unique specialities for improving mechanical properties of nanocomposites such as electrospun nanocomposite fibers/mats and nanocomposite hydrogels. Numerous nanocomposite hydrogels reinforced with CNCs can be designed to be sens...

Titanium Carbide Powders and Applications

Titanium carbide which has the chemical formula of TiC attracted great interest for many structural applications due to its extremely high melting temperature, high hardness, high chemical resistance and good electrical conductivity. Therefore titanium carbide can be used in cutting tools, grinding wheels, wear-resistant coatings, high temperature heat exchangers, magnetic recording heads, turbine engine seals, and bullet-proof vests, etc. In addition, a promising field of application comprises plasma and flame spraying processes in air, where titanium carbide-based powders show high-phase stability. TiC(Titanium Carbide Powder) (325 mesh, 99,9+%)  can also be used in biomedical implant devices. Materials used for biomedical implant devices must satisfy a variety of property demands, which are often mutually exclusive. Further, different parts of a device demand different material properties. These factors often make it difficult to manufacture a medical device using a...
