    摘要: A lithographic method, products obtained thereby and use of the method, in particular, in the production of micro- or nano-metric products or objects. The method includes the steps of deposition of a film of an organometallic solution of a substrate, containing at least one metal ion as precursor(s) for marking the substrate, local exposure, according to the required pattern, of the obtained film, via at least one focussed energetic beam, with an energy density sufficient to at least locally dry the film, dissolution of the non-exposed zone, the at least dried zones remaining on the substrate, optionally subjecting the obtained product to a thermal treatment and, where necessary, repetition of certain steps, with optional change to the organometallic solution, until the required final product is obtained.

    摘要: The present invention relates to a cordierite (2MgO.2Al.sub.2 O.sub.3.5SiO.sub.2) type ceramic powder sintering at low-temperature defined in that its composition is: 60 to 50% SiO.sub.2, 5 to 20% MgO and 20 to 40% Al.sub.2 O.sub.3, and in that its specific surface area is not less than 50 m.sup.2 /g, this powder having a fritting temperature of less than 1,100.degree. C.The invention also relates to a process for the preparation of this powder, which consists in preparing a mixed alcoholic solution of an aluminum and silicon salt, in preparing a solution of an alcohol-soluble magnesium salt, in mixing the two solutions, in padding a hydrolyzing agent in the form of a totally volatile weak base to the solution, which leads to the formation of a gel, in subjecting the said gel to a first thermal treatment at a temperature not exceeding 450.degree. C., and in subjecting the said powder to a second thermal treatment at a temperature of between 450.degree. C. and 900.degree. C.By a sintering which may be carried out at a temperature lower than 950.degree. C., the powder obtained leads to dielectric ceramics which have a coefficient of expansion less than 1.10.sup.-6 C.sup.-1, and a dielectric constant less than 5.
