    • Alkoxy technology is used to prepare composite ceramic materials. The starting compounds for the composite ceramic materials comprise metal alcoholates. The starting alcoholates are prepared by electrode dissolution of metals in a corresponding alcohol in the presence of an electroconductive additive. Such preparation is ecologically safe with no by products other than hydrogen, allows complete regeneration of the electroconductive additive and solvent, and can be continuous or cyclic. A broad range of metal alcoholates can be prepared using the same equipment. Raw composites are prepared with the metal alcoholates and organometallic compounds soluble in organic solvents, followed by solvent removal and hydrolysis. The resultant composite can be applied to a metal substrate or other substrate and once sintered or annealed at the appropriate temperature results in an improved quality, high strength ceramic coating.
    • Alkoxy技术用于制备复合陶瓷材料。 用于复合陶瓷材料的起始化合物包括金属醇化物。 起始的醇化物通过在导电添加剂存在下将金属电极溶解在相应的醇中来制备。 这种制备在生态上是安全的,而不是氢以外的产物,允许导电添加剂和溶剂的完全再生,并且可以是连续的或环状的。 可以使用相同的设备制备宽范围的金属醇化物。 原料复合材料用金属醇化物和可溶于有机溶剂的有机金属化合物制备,然后进行溶剂去除和水解。 所得到的复合材料可以施加到金属基材或其他基材上,并且在适当的温度下进行一次烧结或退火,得到改进的质量,高强度的陶瓷涂层。
