what is the melting point of silica?

Silica is a naturally occurring mineral that occurs both crystalline and amorphous. It is found in a number of natural compounds, including clays, feldspar, olivine, and pyroxene. In addition, it is the primary component of quartz.

Silicon, one of the most abundant elements on earth, is a key ingredient in steel and other metals, and is essential to plant and animal life. It is also used to produce the silicon carbide that forms the hard, durable, and abrasive surfaces of solid-state electronic devices.

How to determine the melting point of a compound

The melting point of a material is usually a critical factor in its application. Knowing this can help you make sure that the metal or alloy you are using will withstand the highest output temperature of your application.

How to prepare a sample for testing

To measure the melting point of a solid, you need a capillary tube, which has one end sealed and the other end open (Figure 6.10). Fill the tube with the solid you wish to test until it is no higher than 22-3mm3mm high in the tube (Figure 6.10d).

Place the tube into a slot behind the viewfinder of a melting point apparatus and adjust the heating rate according to experimentation and experience with the method. When the sample begins to melt, a drop of liquid will appear on the side or bottom of the tube and the first temperature in the melting range will be recorded.
