摘要:
Zircon-containing bodies of very high density and resistance to thermal shock can be made by firing a mixture of comminuted plasma dissociated zircon and an alkaline earth metal oxide and/or transition metal oxide.
摘要:
This invention is concerned with improving the properties of refractory supports used in the manufacture of ceramic articles such as setters, batts, saggars, cranks, stilts, thimbles, saddles and spurs, and resides in the provision on an article-supporting surface of such supports of a coating comprising comminuted plasma dissociated zircon. Also provided is a method of coating refractory supports and a coating composition comprising a dispersion of comminuted plasma dissociated zircon in a carrier liquid.
