Is the silicon carbide crucible good for use? What's the difference between an ordinary graphite crucible and a graphite crucible?
The silicon carbide crucible is a bowl shaped container with a ceramic bottom. When solids have to be heated by fire, the crucible must be used. Because it is more able to withstand high temperatures than glass. When used, the crucible does not usually fill the melt too much to prevent the heat from jumping out and allowing the air to pass in and out freely for possible oxidation. Because the bottom of the pot is very small, it usually needs to be placed on the clay triangle to heat it directly.
Easy to use and convenient.The ordinary graphite crucible can not guarantee the safety in the high temperature environment, moreover, the conduction speed is slow in the test, which is not good for the experiment.
The crucible can be placed on the iron tripod with either positive or oblique directions, and can be placed on the basis of the requirements of the experiment. When the crucible is heated, it cannot be immediately placed on a cold metal table to prevent it from breaking due to rapid cooling. It should not be placed on the wooden table immediately so as not to spoil the table or cause fire. The correct method is to cool the metal on the tripod or to let it cool slowly on the asbestos net. For crucible purposes, see the crucible tongs. The relevant information from the supply of silicon carbide crucible dachengxian Tianjin high silicon carbide crucible crucible factory released using the latest international technology of isostatic pressing method and strict quality assurance inspection system, using advanced refractory raw materials, high-tech formula developed a new generation of high-quality silicon carbide crucible, this product has a large volume density, high temperature resistant, fast heat, acid and alkali resistance, high temperature strength, oxidation resistance and high service life is 3 times that of the clay graphite crucible.
