Alpha alumina has cubic crystal structure, and gamma - rhombohedral (i.e. it is a "skewed cubic")
Due to their geometry the typical surface area of a particle is affected, and alpha alumina has fewer -OH groups than gamma alumina.
Iron oxide can also have either alpha or gamma structure, and is described on wiki http://en.wikipedia.org/wiki/Iron(III)_oxide
Alpha alumina has a hexagonal crystal structure and is thermodynamically stable at high temperatures, while gamma alumina has a cubic crystal structure and is metastable at high temperatures. Gamma alumina typically has a higher surface area and is more reactive compared to alpha alumina.

Nuclear radiation ranked from the greatest mass to the least mass is a- Xray gamma ray beta particle b- Xray beta particle gamma ray c- Alpha particle beta particle gamma ray d Beta alpha gamma?
The correct order is c) Alpha particle, beta particle, gamma ray. Alpha particles have the greatest mass, followed by beta particles, and then gamma rays which have no mass.
What are the symbols for three radioactive particles and waves?
Alpha particle: α Beta particle: β Gamma ray: γ
The least energetic of the forms of radioactive decay is ______?
alpha decay
Mass of alpha beta gamma?
The alpha, beta, and gamma particles have different masses. An alpha particle has a mass of about 4 atomic mass units (u), which is roughly 6.64 x 10^-27 kg. A beta particle (electron or positron) has a much smaller mass, about 0.0005 u or 9.31 x 10^-31 kg. A gamma particle, which is a high-energy photon, has zero rest mass because it is pure energy.
What are AphaGamma Beta rays?
Alpha, beta, and gamma rays are types of ionizing radiation. Alpha rays consist of positively charged particles (helium nuclei), beta rays are either electrons or positrons, and gamma rays are high-energy photons. These types of radiation have different penetrating abilities and biological effects.
What is the difference between alpha beta and gamma hemolysis?
Alpha hemolysis is partial hemolysis resulting in a greenish discoloration of the agar, beta hemolysis is complete hemolysis resulting in a clear zone around the colony, and gamma hemolysis is no hemolysis observed.
What is radioactivity and what is the difference between alpha beta and gamma radiation?
Alpha radiation is helium-4 nuclei - i.e., each alpha particle consists of 2 protons and 2 neutrons.Beta radiation is either electrons or positrons (= anti-electrons). Gamma radiation is high-energy photons.
When was Gamma Alpha created?
Alpha Gamma was created in 1867.
What happens to the energy of a wave as the wavelength of a wave increases?
energy increases, and the wave length decreasespicture the difference between alpha and gamma rays :)
Is there a connection between the speed of alpha beta and gamma radiation which?
beta equal to 2alpha and gamma equal to 3alpha
When was Alpha Beta Gamma created?
Alpha Beta Gamma was created in 1970.
What is Gamma Alpha's motto?
Gamma Alpha's motto is 'Γνωθι την 'Αληθειαν'.
When was Gamma Alpha Omega created?
Alpha Gamma Omega was created on 1927-02-25.
When was Alpha Delta Gamma created?
Alpha Delta Gamma was created on 1924-10-10.
What is Alpha Gamma Omega's motto?
The motto of Alpha Gamma Omega is 'Fraternity for Eternity.'.
When was Phi Alpha Gamma created?
Phi Alpha Gamma was created on 1894-03-25.
When was Alpha Gamma Rho created?
Alpha Gamma Rho was created on 1904-10-10.
