Abstract:
A method for preparing a ferrite magnet, wherein a ferrite having a hexagonal W type magneto-plumbite structure is added to a ferrite which has a hexagonal M type magneto-plumbite structure and in which a part of Sr, Ba, Pb or Ca has been substituted with La and optionally at least one element selected from among rare earth elements including Y and Bi during pulverization to a fine powder; and a ferrite magnet prepared by using the method. The above method which comprises the addition of a ferrite having a hexagonal W type magneto-plumbite structure to a ferrite having a hexagonal M type magneto-plumbite structure during the pulverization allows the preparation of a ferrite magnet having improved magnetic characteristics with the addition of a reduced amount of an element such as Co, Ni, Mn or Zn.

Abstract:
The invention relates to a method for curing a form-supported refractory coating ofxan intermediate vessel. The method comprises mounting a form inside the intermediate vessel, dosing a refractory coating mass essentially in dry existence to the space between an inner surface of the intermediate vessel and an outer surface of the form and applying microwave energy to the refractory coating mass in order to stabilize the mass and bound it to the inner surface of the intermediate vessel.

Abstract:
A coloring solution for dental zirconia ceramics and a method for using the same are provided. The coloring solution consists of coloring agents, a solvent, and an additive. The coloring agents are a combination of two or more rare earth metal compounds, wherein the rare earth metal compounds have rare earth metal ions selected from the group consisting of praseodymium (Pr) ions, erbium (Er) ions, cerium (Ce) ions, and neodymium (Nd) ions. The concentration of the rare earth metal ions in the solution is 0.05-3 mol/liter solvent. The molar ratio of Pr ions : Er ions : Ce ions : Nd ions in the solution is 1 :(10-50):(0-20):(0-30).
