Default Hearth Insulation

I am trying to construct a pizza oven in cambodia and have found it difficult to locate perlite or vermiculite. However in vietnam i came acrosss "perlitesand", Does anybody know what this is and how to use it? i have tried searching online but have had no joy.
If i am unable to locate perlite is there any alternative to this? Could a heat blanket be placed under cement in the hearth or would this be unstable?
There is also a liquid Cal silicate can this be mixed with cement for insulating properties?
