Equipment Requirements

Fluoborate and fluosilicate baths attack equipment made of titanium, neoprene, glass, or other silicated material; thus, these materials should not be used in these solutions. Anode hooks should be made of Monel metal.

Tanks or tank linings should be made of rubber, polypropylene, or other plastic materials inert to the solution. Pumps and filters of type 316 stainless steel or Hastelloy C are satisfactory for intermittent use; for continuous use, however, equipment should be made from or lined with graphite, rubber, polypropylene, or other inert plastic. Filter aids used for the fluoborate solution should be made of cellulose rather than asbestos or diatomaceous earth.
