Aujeszky's disease. Aujeszkyâs disease is a contagious viral disease caused by a herpesvirus called Pseudorabies virus (PRV). The most common form is an acute febrile syndrome that mainly affects pigs (the main reservoir for the virus), though many other animal species are also susceptible.
Used as: anti-caking agent, anti-foaming agent, moisture absorbent, wine and beer fining agent. Definition: Composed of only silicon and oxygen, silicon dioxide is one of the most common anti-caking agents. It is also widely used in the construction and hydraulic fracturing (fracking) industries.uber Engineered Materials. Shanxi Jinjin Chemical Industrial Co., Ltd. wrote that âThere are no animal ingredients in the silicon dioxide.â. Yianlid Industrial Co., Ltd. said in an email that ââ¦There is not any animal content in the [silicon dioxide]â and sent a certificate analysis for silicon dioxide.
Silicon dioxide is suitable for lining furnaces because of its very  high melting point of 1,600 to 1,725 degrees celcius. It is so high  because of the strong intermolecula â¦ r forces between SiO2  molecules in the giant covalent structure comparable to that of  diamond and graphite.A large amount of energy is required to  overcome these intermolecular forces and thus SiO2 has a  high melting point.ilicon dioxide is so important in fabrication process because it exhibits good thermal isolation and also having low thermal conductivity and more it has low thermal expansio â¦ n coefficient.
