In the preparation procedures of this sample, water was removed by evaporation. The obtained samples were dried at 373 K, and powdered through a 32–50 mesh. Thermal decomposition of Mg (OH) 2 into MgO was carried out in a muffle furnace. The hydroxide was placed in the furnace kept at a desired temperature.Use step 10.4.2 if using a muffle furnace with a ramping program. 10.4.1 Ash the samples using a muffle furnace set to 575 + 25 °C. 10.4.1.1 Using an ashing burner and clay triangle with stand, place the crucible over the flame until smoke appears.powdered mgo baked in a muffle furnace at 600 c for 3 hours

3. Dishes, porcelain. Method: Use the residue obtained from ash determination. Boil with 25 ml hydrochloric acid, taking care to avoid spattering, filter through ashless paper and wash with hot water until acid free. Place filter paper and residue into a dry, tared porcelain dish and place in a muffle furnace at 600 C for 2 hours or untilCarefully remove the crucible from the furnace directly into a desiccator and cool. Weigh the crucibles and ash to the nearest 0.1 mg and record the weight. 10.4.2.3. Place the sample back into the muffle furnace at 575 ± 25oC and ash to constant weight. Constant weight is defined as less than ± 0.3 mg change in the weight upon one hour of reLaboratory Analytical Procedure (LAP) Issue Date: 7/17/2005

Muffle furnace
High temperature muffle-furnace, maximum temperature is 1,473 K (1,200 °C; 2,192 °F). A muffle furnace or muffle oven (sometimes retort furnace in historical usage) is a furnace in which the subject material is isolated from the fuel and all of the products of combustion, including gases and flying ash. [1]The effect of the ashing temperature on the physicochemical properties of ashes from Zhundong lignite was investigated. The ash samples were prepared in a muffle furnace in air at ashing temperatures ranging from 550 to 1200 °C and were then subjected to a series of analysis including the yield and chemical compositions Effect of Ashing Temperature on the Physicochemical Properties
