Inhibitors are generally used in mould to avoid reaction of magnesium

1.	Inhibitors are generally used in mould to avoid reaction of magnesium with moulding materials.(a) True(b) FalseI had been asked this question in an international level competition.I'd like to ask this question from Magnesium Alloys topic in chapter Foundry Introduction & Materials of Casting-Forming-Welding II
Answer» Right answer is (a) True Easiest explanation: When moulding materials like silica, moisture and BINDERS make contact with magnesium, the reaction takes place which arise problems in the CASTINGS of magnesium alloys. To AVOID reaction, the mould is MODIFIED by using some techniques like drying and by including INHIBITORS in the moulding materials.
