Can you melt wood? - Chemistry Stack Exchange
2015年5月8日 · Wood is mostly made up of things like cellulose, lignin, and water. As wood combusts, it’s broken down into products like charcoal, water, methanol, and carbon dioxide. Unlike water turning back into ice, if you cooled down the resulting products of burning wood, it obviously does not change back to its original composition.
Why don’t all objects melt and liquefy when heated sufficiently?
2016年11月12日 · Certain objects such as metals, glass, plastic, sugar etc. melt when heated to a certain temperature but other materials such as a piece of wood, paper, a piece of rock etc. do not. Why is that?
How do manufacturer remove oxygen from metal during melting?
2017年6月28日 · There are two aspects to this, firstly is actually reducing the pure metal from its oxides, usually called smelting, most metal ores are metal oxides so this is clearly an important part of primary metal production For example in iron production iron oxides are reduced by carbon, usually from coke which is also the fuel which provides the energy for the reaction.
Will fire corrode stainless steel? - Chemistry Stack Exchange
2015年8月7日 · A wood fire will not be hot enough to cause more than about 0.02" of metal loss in a year of continuous use. This is assuming about 1500 °F. It would make no difference if 410 (13 Cr - exhaust pipes) or 304 or 316 ss is used. If is has …
metallurgy - What is "Woods Metal" - Chemistry Stack Exchange
2017年7月12日 · Wood's metal, also known as Lipowitz's alloy or by the commercial names Cerrobend, Bendalloy, Pewtalloy and MCP 158, is a eutectic, fusible alloy with a melting point of approximately 70 °C (158 °F). It is a eutectic alloy of 50% bismuth, 26.7% lead, 13.3% tin, and 10% cadmium by weight.
Materials that resist adhesion with molten glass even when hot
I'm looking for ways to manipulate molten glass with (e.g. bending a heated glass tube). This article mentions that oxides tend to adhere, hence molten glass to heated stainless steel. What mate...
Isopropyl Alcohol leaves a white haze on plastic, is there anything I ...
2019年5月20日 · Even the common alcohol ( ethanol, ethylalcohol) is known to corrupt surface of some plastics, and rubbing alcohol ( isopropanol, isopropylalcohol) is even better in that, as it contains bigger organic chain and is less polar.
At what temperature does charcoal burn? - Chemistry Stack …
2016年9月28日 · Iron can be melted but furnace construction is a skilled job and the limiting factor in the temperature reached So there is no typical temperature associated with a given fuel. However, you can ask something specific, like about the temperature on the surface of the charcoal when they have burnt for a while.
Material that doesn't melt at 800 deg F, but can be dissolved?
2014年9月23日 · $\begingroup$ @Luke Technically it should not. At least, aluminium/magnesium will dissolve first (though in case of aluminium reaction may start very slowly but react with unhealthy speed once started).
metal - What is the black slag formed when sterling silver is …
2019年1月2日 · The melting is related to jewelry casting. All melting was done in an electric Ney muffle furnace. Here is a melting dish with some half-melted buttons of sterling silver. I can't remember why I didn't completely melt this. I assume the green is salts of copper from the sterling silver. Notice how the black slag erodes the walls of the melting ...
