Boiling Chips, Silicon Carbide | Hach USA - Overview

Carbon boiling chips are chemically inert to concentrated sulfuric acid, strong alkalies, and other chemicals. Carbon chips can be used for atmospheric or vacuum operations. Silicon carbide (carborundum) chips are random-sized pieces up to 2 mm long. Shipping Policy and Rates.

Boiling Chips - Organic Chemistry at CU Boulder

Boiling Chips. Boiling chips are small, insoluble, porous stones made of calcium carbonate or silicon carbide. These stones have pores inside which provide cavities both to trap air and to provide spaces where bubbles of solvent vapor can form. These bubbles ensure even boiling and prevent bumping and boiling over and loss of the solution.

Chapter 5 - Processing of Roots and Tubers - FAO

Chapter 5 - Processing of Roots and Tubers. 5.1 Processing Of Cassava. 5.2 Processing of other Root and Tuber Crops. Chapters 2 and 3 discussed the high moisture content characteristic of roots and tubers which makes them difficult to store for any length of time. Also they are bulky and difficult to handle and transport to distant markets.

When the freshly cut chips have to be kept for prolonged period a preferred treatment is dipping for five minutes in a 0.1-0.2% sodium bisulphite solution, or 10 minutes in a 0.5% sodium metabisulphite solution. After-cooking darkening is the result of the oxidation of ferrous iron present in the tuber to ferric iron.

Silicon is not only used in the construction industry, but high tech equipment like computer chips, solar panels, and transistors are all made up of silicon. The fact that silicon can act as a semiconductor , by allowing control of electrical current, makes it ideal for virtually all electronic equipment.

Boiling chip - Wikipedia

Boiling chips are typically made of a porous material, such as alumina, silicon carbide, calcium carbonate, calcium sulfate, porcelain or carbon, and often have a nonreactive coating of PTFE. This ensures that the boiling chips will provide effective nucleation.
