Calcium Aluminate Cement NA70
The main mineral phase of CA70- is CA,with CA2 as secondary mineral phase ,which has good construction properties, it is good in suitability for the environmental temperature and has a good compatibility for additives.CA70 is suitable to make monolithic refractories, as all kinds of castables,gunning castables. Our company has researched and developed CA70E ,CA70G,CA70A,CA75E,CA75G,CA75A for choice of the customers at the request of the end-users' and to meet changes of the enviromental temperature
