Title:
【発明の名称】金属酸化物組成物を安定化するための添加剤としての低分子量炭水化物
Document Type and Number:
Japanese Patent JPH05504149
Kind Code:
A
Abstract:
This invention relates to compositions comprising a colloidal or particular metal oxide which are stabilized by low molecular weight carbohydrates. The carbohydrates are characterized by the fact that a) they are not retained on the surface of the metal oxide based on the equilibrium room temperature dialysis of about 2 ml of the metal oxide composition at 0.2 M metal concentration against deionized water; and b) they impart sufficient stability to the metal oxide compositions such that the compositions can withstand heat stress without perceptible aggregation as determined by a prescribed test procedure.
