III-VI compound semiconductors include: AlN, GaN, InN, AlP, AlAs, AlSb, GaP, GaAs, GaSb, InP, InAs, InSb, Al x Ga 1-x As and In x Ga 1-x As. Columns II and VI of periodic table, not shown in the figure, also form compound semiconductors.
Hydrofluoric acid | HF - PubChem
Hydrogen fluoride is a colorless, fuming liquid or gas with a strong, irritating odor. It is usually shipped in steel cylinders as a compressed gas. Hydrogen fluoride readily dissolves in water to form colorless hydrofluoric acid solutions; dilute solutions are visibly indistinguishable from water.

Don’t use a carborundum, or silicon-carbide stone, which is very coarse. Although it gives a good edge, it wears your knife down and you want to be able to bequeath it to your grandchildren.

A harder, non-flexible rubber matrix is often used for moulded silicon carbide discs. Synthetic or natural abrasives may be used including. - Silicon carbide (carborundum) - Aluminium oxide - Garnet - Quartz - Pumice - Cuttlebone Cutting mechanism: For cutting it is necessary to apply sufficient pressure to make the cutting edge of a blade or abrasive particle dig into the surface.
What type of circular saw blade do you need to cut …
Carbide-tipped blades last up to 10 times longer than regular steel ones. The pitch and design of the blade you choose will also vary depending on the thickness of the metal in question. In general, you''ll want a higher tooth count for thinner metals and a lower tooth count for thicker ones.

Tantalum | Plansee
Tantalum is a sensible choice whenever high corrosion resistance is required. Even though tantalum is not one of the noble metals, it is comparable to them in terms of chemical resistance. In addition, tantalum is very easy to work at well below room temperature
Metal Carbides - ScienceDirect
On the other hand, the metalloid silicon forms silicon carbide, Sic, a carbide with important industrial and practical uses, both as an abrasive and as a refractory. The major appliions of metallic carbides are as cutting materials (abrasives) or for resistance to high temperatures (refractories); however, a nuer of metals form compounds with carbon having simple formulas, such as CaC2
Boiling chips | Distillation | Solubility
Boiling chips are an old, practical invention rather than an impervious ideal tool, so it is smart to understand why your boiling-chip substance is OK for your appliion. If you are really trying to stay pure, there are at least 4 kinds of substances that boiling chips

Solids - 2012
Elemental silicon has the same structure, as does silicon carbide (SiC), which has alternating C and Si atoms. The structure of crystalline quartz (SiO 2 ), shown in Section 12.1 "Crystalline and Amorphous Solids" , can be viewed as being derived from the structure of silicon by inserting an oxygen atom between each pair of silicon atoms.
15/10/2018· There are many different types of microtome knives (e.g., stainless steel, carbide, diamond, glass, or disposable blades). Wedge-shaped stainless steel knives are used for most paraffin-eedded specimens. They must be kept clean and well-oiled or lubried.

Silicon carbide or steel shots mixed with water are used as cutting media. Wire saws being although cheaper are not capable of yielding a high rate of production. An advantage to wire sawing is that it produces a smooth cut which minimizes the subsequent dressing cost.
