Barium hydroxide octahydrate
Barium Hydroxide
Barium hydroxide, a chemical compound with the chemical formula Ba(OH)2, is white solid substance, soluble in water, the solution is called barite water, strong alkaline. Barium Hydroxide has another name, namely: caustic barite, barium hydrate. The monohydrate (x = 1), known as baryta or baryta-water, is one of the principal compounds of barium. This white granular monohydrate is the usual commercial form. Barium Hydroxide Octahydrate, as a highly water insoluble crystalline Barium source, is an inorganic chemical compound that is one of the most dangerous chemicals used in the laboratory. Ba(OH)2.8H2O is a colorless crystal at room temperature. It has a density of 2.18g / cm3, water soluble and acid, toxic, can cause damage to the nervous system and digestive system. Ba(OH)2.8H2O is corrosive, may cause burns to eye and skin. It may cause digestive tract irratation if swallowed. Example Reactions: • Ba(OH)2.8H2O + 2NH4SCN = Ba(SCN)2 + 10H2O + 2NH3
high grade Cerium Oxide
Cerium(Ce) Oxide
Cerium Oxide, also known as cerium dioxide, Cerium(IV) Oxide or cerium dioxide, is an oxide of the rare-earth metal cerium. It is a pale yellow-white powder with the chemical formula CeO2. It is an important commercial product and an intermediate in the purification of the element from the ores. The distinctive property of this material is its reversible conversion to a non-stoichiometric oxide.

CZC (Ceria Stabilized Zirconia Bead) is a high density zirconia bead that is suitable for large capacity vertical mills for dispersion of CaCO3. It has been applied to the grinding CaCO3 for high viscosity paper coating. It is also suitable for the production of high-viscosity paints and inks.
Aluminum Oxide
Aluminum Oxide (Al2O3) is a white or nearly colourless crystalline substance, and a chemical compound of aluminum and oxygent.  It is made from bauxite and commonly called alumina and may also be called aloxide, aloxite, or alundum depending on particular forms or applications.  Al2O3 is significant in its use to produce aluminum metal, as an abrasive owing to its hardness, and as a refractory material owing to its high melting point.
Cerium(III) Oxalate
Cerium(III) Oxalate Hydrate
Cerium(III) Oxalate (Cerous Oxalate) is the inorganic cerium salt of oxalic acid, which is highly insoluble in water and converts to the oxide when heated (calcined). It is a white crystalline solid with the chemical formula of Ce2(C2O4)3. It could be obtained by the reaction of oxalic acid with cerium(III) chloride.
