The terms solidus and liquidus are useful in many different fields, including chemistry, material science, and physics. The key difference between solidus and liquidus is that solidus temperature quantifies the temperature at which the substance becomes completely solidified, whereas liquidus temperature ...
The O−O group in a peroxide is called the peroxide group or peroxo group. Dioxide A compound with two oxygen atoms per molecule. Peroxide The divalent O2 group, or a compound containing this group, such as sodium peroxide, Na2O2, used as an oxidizing agent or bleach. Dioxide (chemistry...
Study of silica coated magnetite particles (Fe3O4/SiO2) indicated that saturation magnetization is lower than Fe3O4 [11]. The surface area of composite decreased with increasing content of Fe3O4, because most of the pores in the bentonite blocking with Fe3O4. Futhermore, BET surface 545 ...

What is silica oxide? Silicon dioxide (SiO2), also known as silica, isa natural compound made of two of the earth's most abundant materials: silicon (Si) and oxygen (O2). Silicon dioxide is most often recognized in the form of quartz. ... It makes up more than 95 percent of known ...
Glass isn’t just SiO2 January 29th, 2011 at 4:34 pm (Chemistry,History) It happened so long ago that it’s not really known how glass was first discovered. Certainly, lightning can strike a sandy beach and fuse silicon into glass bits (calledfulgurites). The lightning has to reach 327...
in France, you’ll immediately bump into a giant display of thermal water spray cans. A whole host of French skin care brands likeAvène, La Roche-Posay, Uriage and Vichy sell thermal water sprays. What is it, what’s in it, what does it do and how is it different from regular ...
