What is ultramarine blue made from?

The current synthesis process for the ultramarine pigment, based on the process discovered by Guimet, consists of heating a mixture of metakaolin, sodium carbonate, sulfur and a reducer. These reagents are mixed in the desired proportions, then are calcined in furnaces. Ultramarine blue calcination process calcined ultramarine pigment is a very complex process, to consider many features to adapt the conditions to complete the reaction. According to different calcination ultramarine pigmentstove, can be divided into a se aled tube furnace, crucible furnace, muffle furnace and other production methods. Sealed tube furnace production is the manufacture of solid-phase method ultramarine blue more advanced methods, which can make the process manufacturing ultramarine blue to mechanization and automation proceed. The temperature cycle is comprised of several steps: heating to 800° C. in the absence of air, followed by an oxidation step at a lower temperature.Currently only a few countries in the world produced by this method. China currently uses a crucible furnace calcination ultramarine pigmentinverted smoke.The pretreated feedstock, according to a certain formula evenly mixed, compacted into the crucible; the loading capped crucible, preferably sealed with mud, pour code in the crucible, the closed door, and calcined to flocks of blue firing crude products.Ultramarine blue because the calcination carried out during the gas exchange, it requires the crucible is porous. Select the appropriate porosity, the reaction is complete the necessary condition ultramarine pigment. Fineness according to charge, the charge density of the crucible, furnace structure and size, process control conditions, the porosity of the crucible have different requirements.http://www.xcolorpigment.com/news/?44.html

What is function of muffle furnace in lab?

A muffle furnace, is an oven type equipment, that can reach high temperatures. The use of a muffle furnace is to burn off specific types of compounds. For instance, for a standard determination of the amount of inorganic components within an object, a muffle furnace can be used to burn off all the organic material (which is roughly said always < 500 oC). It principle thereof is plainly to auto-ignite the organic material, due to high temperatures

Muffle furnace and its uses in a Pharmacognosy lab?

A furnace is a scientific appliance used to generate heat in a controlled manner for various purposes like heat treatments and drying procedures. One such furnace is a muffle furnace. This article explains a muffle furnace and its uses and applications. Muffle Furnace A muffle furnace is a type of furnace, i.e., an instrument used to create an environment with high temperatures for processes like curing, drying, and heat treatments in chemical procedures. In a muffle furnace, heat is generated by the combustion of various types of fuel products. The objects kept inside the oven are heated only by the heat radiated into the oven and not by direct flame. Heat transfer in a muffle furnace takes place due to convection. The objects do not come in contact with the flame or the residues of combustion like smoke and ash. The word ‘muffle’ is used because the insulation in the furnace prevents the heat generated inside the chamber from escaping. Heat spreads uniformly throughout the chamber. The temperature inside the chamber is controlled and maintained throughout the process. Now, we have seen what a muffle furnace is. But how is it used in a pharmacognosy lab? Let us see. What is Pharmacognosy? Pharmacognosy is the science of drugs and medicines obtained from natural resources like plants and animals. It also studies the properties of these drugs. E.g., Medical Cannabis or CBD is obtained from the flower of the plant Cannabis. It is a powerful drug used for the treatment of many psychotic illnesses. The crude drug is obtained from plants and other natural sources. They undergo further chemical and heat treatments and are transformed into the consumable medication of a certain quantity and quality. Muffle Furnace in Pharmacognosy How is a muffle furnace used in a Pharmacognosy laboratory? The crude drugs extracted from plants and many natural sources are subjected to very high temperatures to study the changes in their properties. Another use of a muffle furnace in a pharmacognosy lab or any pharmaceutical laboratory is for drying and coating purposes. The excess moisture is removed from the tablets and they are coated (toughened). Features of a Muffle Furnace · Heat resistant fragments · Cooling fans to prevent over-heating · Uniform heating · Accurate temperatures maintained continuously · Energy and space-saving Muffle Furnace service in Chennai MRS Scientific Instruments Company is a leading manufacturer of scientific and laboratory instruments like Furnaces, Incubators, Ovens, etc. They provide affordable, high-quality Muffle Furnace services in Chennai.
